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.
NEW YORK, Dec. 1, 2017 /PRNewswire/ -- Grayscale Investments, LLC, the sponsor (the "Sponsor") of the Bitcoin Investment Trust (OTCQX: GBTC) (the "Trust"), announced that it has irrevocably abandoned (i) all of the rights to Bitcoin Diamond tokens currently held by the Trust as a result of the fork in the Bitcoin blockchain on November 24, 2017 and (ii) all of the rights to Bytether tokens currently held by the Trust as a result of the fork in the Bitcoin blockchain on August 1, 2017.
Anonymous / private Bitcoin. Now, you may think, “What are you talking about? The BTC is anonymous already.”  This is a very unfortunate albeit popular misconception. All BTC transactions can be seen by the public, and by giving out your wallet address to someone, the person is able to see all the payments you’ve sent and received. The black market (weapon manufacturers and drug dealers) created a solution for this. They basically created software that mixes your coins with other coins. Nevertheless, the software needs to be trusted and may not work correctly, which is pretty bad when your freedom depends on it. Monero has the mixing system built-in. This makes it perfect for any kind of black market.  A popular darknet market adopted Monero, and this is how the currency got its first big growth boost.
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.

I don't know where this is going to go. And let me let you in on a little secret. Neither do you. One thing I know to be true, that has played out throughout history over and over across several different landscapes, be it political, economic, science and technology, etc is the following... It only takes about .00001% percent of the RIGHT part of the population to get on board with an idea whose time has come. ( 1.) The colonies should declare independence from Great Britain (The American Revolution) , 2.) Free men should not be able to be imprisoned or whimsically taxed by the king (The Magna Carta) 3.) Powered flight is possible (The Wright Brothers, etc) 4.) Racial discrimination should not be supported by the state (Martin Luther King) 4.) The Catholic Church is not only not infallible, but is corrupt and we need to split from it (Martin Luther) 5.) It is stupid to build a rocket, launch it, and then crash into the ocean (Elon Musk) etc. etc. etc. All that being said I think I can make the following statement with absolute confidence. *** Given the perceived injustice and full display of avarice perpetrated by the global central banks, the banking/finance guild/medical guild (to include healthcare, insurance, drug companies etc), the global political class, and the amount of leverage/debt and soon to be unfulfilled social contract promises and the corresponding counterparty risk/chain of custody issues AND given the GLOBAL talent pool that is lining up behind ico's/blockchain in all its use cases to think that revolutionary change is not only possible but imminent would seem very likely to be a suckers bet. It is worth keeping in mind that MOST of the rational sounding population will dismiss this idea out of hand. People that are "rational' in a fucked up world are in effect the radicals and mean reversion both illustrates this in hindsight, and prunes their belief systems and all the structures and constructs that those flawed belief systems were supporting from existence. The current global situation seems to be very near full term pregnant with crisis and opportunity.
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.
There is one risk involved with stop-losses because of this though, which is when a price drastically drops. This is because a stop-loss is automatically triggered once the price threshold is reached. It could be that the price plummets so hard that the stop-loss sells for a far lower price than you anticipated. This is because during a crash, a lot of people are selling but nobody’s buying, meaning the price can only be determined once anyone buys. Using the example above, if Lisk were to drop from $32 to $27 without anyone buying in between, your stop loss would sell at $27.

The cryptocurrency market has returned over 900% since the beginning of 2017 (at the time of writing this). You cannot find these kinds of return on investments in the stock market or anywhere. If you had made an investment of $500 in January, you would have made $5000 in less than a year (!). This type of strategy is known as long-term investing, and this guide is aiming to show you how to implement this investment method – to construct a long-term cryptocurrency portfolio.

We think that cryptocurrencies may be the opportunity of a lifetime. The market is still immature and relatively small. However, 2018 has seen the entry of well respected financial players into the space such as George Soros and the Rockefellers. We still think we are in the first innings in cryptocurrency and believe that as more large financial players enter the market, that there is the potential for extraordinary gains.

Steindorff: QTUM is an emerging smart-contract platform with a strong team and promising future. You can think of QTUM as a bitcoin/ethereum hybrid in the sense that the platform enables smart contracts to be built atop bitcoin’s UTXO blockchain. This is an important technological achievement as it enables mobile and IoT compatibility for smart contract backed decentralized applications, a feature not currently available with Ethereum. Mobile compatibility will accelerate the proliferation of smart-contract adoption among businesses while simultaneously broadening its use case as a digital currency via mobile friendly QTUM wallets. Additionally, QTUM has shifted away from the Proof of Work consensus model (Bitcoin/Ethereum) and instead leverages the Proof of Stake model which rewards QTUM token owners for confirming transactions via “staking” instead of “mining.” Without getting into too many details this method is both more environmentally friendly and less prohibitive for individuals to participate than the Proof of Work method.  Since launching in early 2017 QTUM has garnered a massive community throughout the Asia-Pacific and the United States. We believe the QTUM team is unrivalled in Asia and their protocol stack has the potential to become the dominant Smart Contract platform of Asia. 
Second: Investment in cryptocurrency isn’t something to be taken lightly. It’s extremely risky, extremely speculative, and extremely early stage still at this point in time. Countless speculators and day traders have lost their entire fortunes trading cryptocurrency. I was no different when I first started investing in crypto. The first $5000 I put into crypto fell almost immediately to less than $500 — a net loss of over 90%.
To define this they use custom questionnaires which help to explore aspects such as age and size of the current investment portfolio or profession. For example, it is considered that retired elementary school teachers tend to fall into the cautious group of investors, architects and engineers are usually placed to the methodical group, while salespersons are more spontaneous in their investments.

Virtual currencies, including bitcoin, experience significant price volatility. Fluctuations in the underlying virtual currency's value between the time you place a trade for a virtual currency futures contract and the time you attempt to liquidate it will affect the value of your futures contract and the potential profit and losses related to it. Investors must be very cautious and monitor any investment that they make.
