As a general rule, what goes up can come down, and what goes up particularly quickly is privy to come down just as quickly. This is not to say that things will come down if they go up, but merely that they can, and certainly have before. This is particularly noteworthy today, with ethereum having seen some truly wild gains this year, all the way up from $7 back in December of last year to over $350 presently — a gain of 50X in just about half a year. Again, this isn’t to say ethereum will fall, but merely that it very well might, for any host of reasons, and it’s very important to keep this fact in mind and not overextend yourself with investments you perceive to be less volatile than they truly are. I’ll get back to this more later.
Be skeptical of the hype. According to Welch, “in every way, the cryptocurrency market is a flow of supply and demand.” It’s one of the reasons it fluctuates so wildly. “When you see a lot of hype and excitement around a volatile investment that depends on supply and demand, take pause and look at what’s really going on.” He advises to take caution when you start to hear phrases like “get it before it’s gone” and “you won’t want to miss out on this.” A lot of hype can often be the precursor to a crash.

This article is a very high level introduction to the Grayscale Bitcoin Investment Trust (OTCQX:GBTC). If you are unsure about what Bitcoin (BTC-USD) is, then you can start by reading some of my articles on the subject. Alternatively, if you're a visual learner there are many great videos that can get you up to a basic level of understanding. Let's begin.
As the Chicago Board Options Exchange launched cash-settled Bitcoin futures trading on December 11, and their rivals Chicago Mercantile Exchange followed suit six day later, prices of both BTC derivatives and the coin itself surged amid an unprecedented wave of publicity. Each Cboe contract was for one Bitcoin, while each CME futures represented five. Both enabled traders to take either long (agreement to buy) or short (agreement to sell) positions, meaning that investors could bet on both increase and decline of Bitcoin price.
This is just my 0.02$, as always, I can be completely wrong, and I maintain the right to contradict myself in the future.

It was at this time, incidentally, that Coinbase, became worried about stagnant growth of their user base, and decided to offer a truly astounding proposition. They offered to pay anyone who referred a new customer to Coinbase $75 if the new customer purchased just $100 in bitcoin. Coinbase took a 1% transaction fee at the time, meaning that for every $100 in bitcoin a person purchased, Coinbase charged $1. In short, Coinbase would pay out $75 for every $1 a new customer paid them.

It is when the next financial crisis happens and people are locked out of their bank accounts that they will see the power of crypto and bitcoin (think Greece and Cyprus). Outside of precious metals there is no other escape from the corrupt debt based fractional reserve monetary system the world is trapped in -- Also, there are like 3 billion people in the world that are unbanked -- that alone should get someone to take 1 percent of their net worth into crypto -- the risk reward is insane. As far as the criminal activity in bitcoin LOL!!! OMG banks have committed more fraud and crimes and nothing happens to them. Under federal and state laws known as civil forfeiture, police can seize cash or property if they suspect it's tied to an illegal activity even if the property owner isn't charged with a crime -- Supreme Court has upheld this. I am sorry I do not trust governments (who in their right mind would) and am glad there is a place I can hold some of my wealth outside of their reach.
Indeed, some market movements are fundamentally unpredictable in their short term timing. Two very vivid examples of this were the collapse of Mt Gox for bitcoin, and the hacking of the DAO for ethereum. Both of these events absolutely cratered the price of bitcoin and ethereum respectively, and both of them were fundamentally unpredictable in their exact timing. These are examples of the black swan events I mentioned that are certain to continue playing a large role in short term price developments for bitcoin and all other cryptocurrencies at large, that make it doubly dangerous for those who day trade.
No. 3: Institutional quality custody solutions could come to market soon: There is an urgent need for qualified custodians to safeguard the growing amount of crypto assets. Very few crypto custodians meet the strict security requirements demanded by regulators and institutional investors. Coinbase, one of the more popular exchanges, has launched custody services by partnering with Electronic Transaction Clearing (ETC), a regulated broker-dealer. ItBit and Xapo have also begun to offer similar services and we expect more to follow.
This option is most similar to using a credit card but without the associated risks of interest rates. You can use a standard debit card that is connected to your checking account, or you can buy a prepaid card. Using a debit card is widely accepted on most exchanges and instantly transfers, meaning you won’t have to worry about Bitcoin prices fluctuating before the transfer is complete.
Cryptocurrencies really are one of the most volatile investments anyone can make. Yes, it’s possible to strike gold in cryptocurrency and we are sure you have heard of all these cryptocurrency millionaires. The reality is that it takes time for your portfolio to grow and these Bitcoin millionaires that you hear about got in exceptionally early and in some cases waited 8 years to see exciting returns.

Steindorff: Litecoin. LTC taught us a very valuable lesson about the strength of a brand and its corresponding community. We missed the boat on LTC early on because we felt that its use case overlapped too heavily with BTC. It was hard to imagine that LTC could gain any significant market share from its dominant predecessor but despite our beliefs, Litecoin’s brand and community have driven it to become a top 10 cryptocurrency with a lot of volume and liquidity. The lesson here was that the power of a trusted brand and a devoted community has the ability to outweigh innovative tech. 

The simplest example is flipping a coin. This will yield heads 50% of the time, and tails 50% of the time. Expected value of betting on the coin yielding heads, hence, is 0. This is because in any one given flip, the coin has exactly a 50% chance of coming up heads. Hence, if you bet $100 on the coin coming up heads an infinite number of times, your expected gain, or value, from such an action, is to be $0.
Cryptocurrency is a digital currency, encrypted and used as a medium of echange for financial transactions that uses strong cryptography, to secure transactions, control the creation of new units and to veryfy the transfer of the assets. The validity of each cryptocurrency's coins is provided by a blockchain, a list of records or blocks secured by cryptography.There are many crypto currency actually, we focused on Bitcoin, Ethereum and Litecoin.

The introduction of child chains opens up great levels of customisation. It also enables each child chain (which could be a group, institution, private/public organisation, company, etc.) to run its own self contained blockchain ecosystem whilst still benefitting from all the core features of Ardor itself. These features can also be turned on and off as per the requirements of that given project. This feature makes Ardor a very attractive platform for a wide range of use cases.

A long time horizon also gives us the opportunity of compounding gains over time. Look at the cryptocurrency market as the challenge to find the next Amazon and potentially enjoy larger long term gains. Who wants to be the type of guys to sell Amazon when they were up a little in the year 2000 and miss out on nearly two decades of heavy gains? Also, if you are convinced about the long term growth potential of a cryptocurrency project, why sell it in a few months time?

WAX (World Asset Exchange) is an emerging project with a bright future. Developed by the founders of OPSkins, the leading marketplace for virtual video game assets. The WAX team has built the first decentralized exchange for gamers to trade digital-assets for nominal fees on a trusted platform. There’s a massive market for this platform considering there are over 400 million gamers who purchase more than $50B in digital goods every year. WAX is one of the few emerging projects with a built-in use case and existing user base which already has experience using cryptocurrencies to purchase digital assets. 
As the tech literacy of the population increases, acceptance of crypto as a legitimate store of value follows, and it boomed. Titles along the lines of ‘Bitcoin price hits new all-time high’ and ‘Ethereum price surges’ are starting to perforate the general public’s news feed. What we know for sure is that people who were once skeptical of Bitcoin and the technology behind it are slowly understanding and getting increasingly involved with crypto. As at the time of writing, the market cap of the entire crypto space is at 30.9 billion USD. It was 20 billion just four months ago. What would it be four months from now?
It’s important that enough miners keep trying to mine blocks because this is another valuable service miners provide the network. Bitcoin, like gold, is powerful as a store of value because it is decentralized and trustless. There is no one central authority who holds all the power over bitcoin, just like no central authority holds power over gold.

First, there's a clear lack of differentiation. There are, as noted, over 1,600 investable cryptocurrencies for folks to choose from. That's simply too many. You could probably get rid of 1,500 of them, and virtual currency investors would still struggle to keep track of the partnerships, projects, and missions of each of the remaining digital currencies. It's just impossible to weed out which virtual currencies have staying potential and which don't.

Gold holds its value well because we trust that we will all collectively continue to trust it as a store of value forever, predominantly due to its scarcity and lack of centralized control. Fiat currencies hold their value well when they do because people trust that everyone else trusts the currency as well, and that it is deserving of trust. The moment that collective trust collapses, so too does the currency, no matter what its intrinsic ‘tangible’ value.

For me, security tokens are too risky at the moment – take, for example, the SEC’s recent witch hunt, during which it subpoenaed 80 cryptocurrency companies. However, the tokenized model of securities has the potential to severely disrupt current fundraising and shareholding models. Once global regulatory bodies have created a clear regulatory framework to reduce their risk, investing in security tokens will become a highly attractive option.
No. 4: Cryptocurrency futures, derivatives, and forward contracts are gaining adoption: The volatility of crypto prices at the beginning of the year dramatically boosted demand for crypto derivative products. With derivatives, investors do not need to hold the underlying crypto asset, but they can still enjoy the potential benefits while possibly minimizing loses, much like they hedge regular currencies. While many exchanges do not yet allow direct sales of Bitcoin, investors can speculate on cryptocurrency pricing by trading futures on exchanges like BitMEX, LedgerX and OKCoin. Institutional investors have used futures contracts to even influence crypto currency prices, especially BTC. In the United States, the move by the Chicago Mercantile Exchange and Chicago Board of Exchange to offer futures trading has further validated the industry.
