This is where the ‘crypto’, incidentally, in cryptocurrency comes from. Cryptographic hash functions are fundamentally necessary for the functioning of bitcoin and other cryptocurrencies, as they are one-way functions. One-way functions work such that it is easy to calculate an output given an input, but near impossible to calculate the original input given the output. Hence, cryptographic one-way hash functions enable bitcoin’s proof of work system, as it ensures that it is nigh-impossible for someone to just see the output required to unlock new bitcoins, and calculate in reverse the input that created that output.
A cryptocurrency is a digital currency that is created and managed through the use of advanced encryption techniques known as cryptography. Cryptocurrency made the leap from being an academic concept to (virtual) reality with the creation of Bitcoin in 2009. While Bitcoin attracted a growing following in subsequent years, it captured significant investor and media attention in April 2013 when it peaked at a record $266 per bitcoin after surging 10-fold in the preceding two months. Bitcoin sported a market value of over $2 billion at its peak, but a 50% plunge shortly thereafter sparked a raging debate about the future of cryptocurrencies in general and Bitcoin in particular. So, will these alternative currencies eventually supplant conventional currencies and become as ubiquitous as dollars and euros someday? Or are cryptocurrencies a passing fad that will flame out before long? The answer lies with Bitcoin.
I’m in it for the long term and I don’t focus on daytrading, ever. However (and it took me a while to understand this), HODLing isn’t always the best way to fly either. Yes, the market is still in its infancy, and the new Googles and Facebooks may already be listed on Coinmarketcap and perhaps even in your portfolio. But your portfolio can be worth much more with a measured strategy, instead of passively HODLing. And let’s be honest, at least half of your motivation to buy crypto is to make a lot money.
With something as speculative as cryptocurrency in the first place, it makes no sense to invest in this space to begin with if your only goal is to make 20% profit. It almost certainly isn’t worth the risk at that level of gain. Hence, risking losing out on the long term upside of 10X+ that you’ve calculated and come to the conclusion does exist for a gain of less than 1X or .5X in most cases makes little to no sense at all. It only makes sense if it’s essentially a guaranteed gain with no risk, and that, again, is almost certainly not the case.
The emergence of Bitcoin has sparked a debate about its future and that of other cryptocurrencies. Despite Bitcoin’s recent issues, its success since its 2009 launch has inspired the creation of alternative cryptocurrencies such as Litecoin, Ripple and MintChip. A cryptocurrency that aspires to become part of the mainstream financial system would have to satisfy very divergent criteria. While that possibility looks remote, there is little doubt that Bitcoin’s success or failure in dealing with the challenges it faces may determine the fortunes of other cryptocurrencies in the years ahead.
So, unlike an ETF, the amount of Bitcoin held does not increase or decrease from market activity like people buying in or selling out (with the exception of new entrants who must be accredited investors, and in that case they must wait a full year to trade their shares). This creates a situation where the amount of Bitcoin purchased with a single share of GBTC does not always equate to the fair market value of the underlying asset.
This occurs because any block that the rogue miner who changed their software mines won’t be accepted by all the other miners who are still running the original software. Consequently, all the other miners will begin mining different blocks, and adding those to their blockchain. This leads to a fork in the road, essentially, where two completely different blockchains are formed — one by the rogue miner, and one by all the other miners.

You would have heard of Bitcoin and the ‘altcoins.’ How this naming convention started was because back in the days of 2011, forks of Bitcoin appeared in the markets. The forks, or clones, each aspire to serve a niche area, aiming to be ‘better’ than Bitcoin. Since then countless new crypto has emerged, eroding away Bitcoin’s crypto market cap dominance. These altcoins are gaining market share at an alarming speed. Ten times or more growth has been observed in a time span as short as six weeks (see PIVX, an altcoin).
The most common place where people buy and trade cryptocurrency is on the exchanges. Exchanges are places where you may buy and sell your crypto, using fiat. There are multiple measures to judge the reliability and quality of an exchange, such as liquidity, spread, fees, purchase and withdrawal limits, trading volume, security, insurance, user-friendliness. Out of all these, I find Coinbase as the best exchange hands down. It has a beginner-friendly user interface, and an unbeatable 100% crypto insurance.
Zcash is a crypto that aims to solve the same issues Monero does. Zcash leverages zero-knowledge proof constructions called zk-SNARKs. These constructions allow two users to exchange information without revealing their identities. The bitcoin blockchain contains records of the participants in a transaction, as well as the amount involved. On the other hand, Zcash’s blockchain shows only that a transaction took place, not who was involved or what the amount was.
Some bitcoin exchanges allow account holders to short — bet that bitcoin will fall in value — but the ordinary investor cannot do this as easily with bitcoin as with stocks or exchange-traded funds. Shorting is easy on the futures markets, however, as the trader simply buys a contract to sell a block of bitcoin at today's price sometime in the future. If it works out the price will fall and the bet will pay the difference.

Even though rebalancing means a bit more work (there’s no portfolio tracker to my knowledge that does this yet), you can use this method to establish the relative presence of an overarching type of coin in your portfolio, like the financial transactions/protocol/utility coin distribution. Are utility tokens taking up a bigger and bigger part of your entire portfolio? Then it’s a good idea to identify why this is happening and consider selling some of the leading utility tokens to buy some more transaction or protocol coins.
Factom is useful for all kinds of business apps, and they have got a huge contract with more than 25 smart cities in China. They are also working with other countries to create immutable database, which will allow government to secure their data. Factom had initially raised 5.3 million dollars in its Series A funding, but the company is so appealing that private investors were compelled to increase their investment in Factom. Factom raised a total of 8 million dollars in April 2017 from various high-profile investors, including Tim Draper, Stewart Title, and Bill Gates. See more on Factom cryptocurrency here.

A bitcoin is a virtual currency first introduced in the year 2008 by an anonymous group called Satoshi Nakamoto. It’s an open source peer-to-peer cryptographical system (direct connections without an intermediary) where transactions happen through a public ledger called blockchain, handling users’ data anonymously. Eight years since its introduction, bitcoin is today the most widely used and accepted digital currency.
On June 26, the SEC revealed a proposal to ease the approval process and “modernize the regulatory framework for exchange-traded funds.” Most notably, the proposal stated that the “cost and delay of obtaining an exemptive order” during application would be eliminated, lowering the market barrier to entry for innovative new ETFs backed by cryptocurrencies.
*An accredited investor, in the context of a natural person, includes anyone who either earned income that exceeded $200,000 (or $300,000 together with a spouse) in each of the prior two years, and reasonably expects the same for the current year, OR, has a net worth over $1 million, either alone or together with a spouse (excluding the value of the person’s primary residence).
Now that the benefits of a long term-investment strategy have been made clear, it is also important to consider which cryptocurrencies you want in your long-term portfolio, or how to build your portfolio. Before that, let’s identify some indicators that we can use to measure the potential of the crypto project in the long term. These are just a few indicators that we have identified; feel free to include yours in the comments section below.
The appeal for many is the fact that Bitcoin is decentralized, meaning no specific group or governing body has control over it. Instead, it is secured by advanced cryptography, a set of military-grade encryptions, and regulated by a network called the Blockchain. The Blockchain acts as a digital ledger, confirming buyer/seller funds and establishing the order in which transactions take place.

A rising trend in the world of cryptocurrencies, Bitcoin ATMs allow users to purchase Bitcoin with cash through machines that work almost identically to standard ATMs. With over 3,000 Bitcoin ATMs scattered across the world (primarily in large metro areas throughout North America and Europe), you can use search tools such as Google Maps or Bitcoin ATM Radar to find one close. Just remember that while Bitcoin ATMs have low processing fees, they also have a low buying limit.
Merchants must be wary of their customers, hassling them for more information than they would otherwise need. A certain percentage of fraud is accepted as unavoidable. These costs and payment uncertainties can be avoided in person by using physical currency, but no mechanism exists to make payments over a communications channel without a trusted party.

Consequently, all the other miners will begin mining different blocks, and adding those to their blockchain.

Great to get an update on this new asset class. I think any of us who ignore or dismiss cryptos are potentially missing a huge opportunity. As Dan says the risk reward is assymetric so why would anybody with a pragmatic attitude to investment not have at least a minimal exposure? Unfortunately too many people are happy to buy the negative propoganda of yesterday's winners like Jamie Dimon and Charlie Munger for whom the answer to the question of will bitcoin go to zero or a million will never matter! For most of the rest of us, we want to listen to the pros and cons of the narrative. Thanks RVTV for giving this important new asset class airtime. I would welcome more informative videos like this on cryptos.

You might buy in to your Ethereum position at $1000, you set your sell position $1300. Your sell order could take days, weeks, months, years or till the end of time to be filled. Once it has been filled, you then take that profit and you roll it over in to a new buy over at, say, $1100. Choosing good targets for your buy and sell orders is crucial if you want to be a successful swing trader but overall swing trading cryptocurrency is pretty easy – set your orders and then just wait.

Any cryptocurrency other than bitcoin is referred to as an altcoin. Remember, you should treat cryptocurrencies as if you were a VC looking to invest in a startup. You’d invest in the startup that would have the greatest chance of succeeding because it provides a unique benefit to the world that will continue to be useful in the long run. The main wallet i’m using to invest in altcoins is CoinSpot because it gives me the option of purchasing a plethora of cryptocurrencies from just one account.
There are already a number of proposed solutions to this issue, such as the implementation of the Lightning Network, but in order to implement these solutions, the majority of bitcoin miners must agree to update their bitcoin software. Many bitcoin miners are reluctant to do so, in large part because high transaction fees are good for miners, at least on a short term basis, as it means they earn far more per each block mined. The implementation of the Lightning Network and other solutions threatens to take away this extra revenue stream. Hence, users of bitcoin and miners of bitcoin find themselves at odds with a very understandable conflict of interest. It’s unclear as of yet how this will be resolved, though it seems the community is pushing forward towards a resolution, and I’m of the personal belief that they’ll get there eventually.
This system holds a lot of advantages even over gold’s natural system of being mined out of the ground. Gold’s mining is effectively random and not dictated by any perfect computer algorithm, and is consequently much more unpredictable in its output at any given moment. If a huge supply of gold is serendipitously found somewhere, it could theoretically dramatically inflate the rate at which gold enters the existing supply, and consequently cause an unanticipated decrease in the unit price of gold.
Because of this, I actually personally keep my cryptocurrency distributed in several reasonably safe baskets. For instance, despite Coinbase being an exchange that fundamentally requires some trust, they are more trustworthy than almost any other exchange on a technical level (their customer service, however, leaves something to be desired), and it is virtually impossible for their coins to be hacked to any significant degree, and all those at risk of being hacked are fully insured. As a consequence, I leave some of my coins with them, merely because in many ways, I trust their technical security measures more than I trust my own. Before GBTC started trading at such an absurd premium, I also kept some of my funds with them, both in part to diversify across multiple platforms to reduce the risk of losing all my coins with one bad black swan event, and also because it was the only immediately easy way to put some of my retirement funds into bitcoin, short of creating a self directed IRA.

The market is so volatile that big movements up and down are pretty common and you can capitalise on this through swing trading. I recommend choosing a group of coins to be in and then sticking to swing trading in those coins rather than jumping constantly between different cryptocurrencies – it does help to have an understanding of what different coins do and how much volatility can be expected and you will gain that understanding with time. Good luck!
What’s also striking is that traditionally, these sorts of ‘angel or seed’ investments in new technologies have been closed off to all but an incredibly well connected inner circle of elite high net-worth individuals and institutions. Peter Thiel, for instance, was only approached to become Facebook’s first outside investor because he was already incredibly well known within Silicon Valley for having founded and sold PayPal for over a billion dollars. In contrast, with bitcoin, a random student in Norway was able to invest just $27 and make millions.
