Why can the bitcoin be a major threat to the market next year? (1)

The bitcoin and the other cryptocurrencies are the hot topic of 2017. The bitcoin has risen 17 times since the beginning of the year, and other cryptocurrencies, like the lightcoin and the ripple, have multiplied their value by more than 50 times.
Still, not all experts are so enthusiastic about the future of cryptocurrencies and their impact on global financial markets.
Although futures were shown on the bitcoin of two of the leading derivatives exchanges and in the second half of next year, as Nasdaq is expected to do so, according to Michael Backpack of HighTower, cryptocurrencies may be the basis for serious problems for financial markets as a whole in the coming year. Here's the reasons for these expectations:
Firstly, at the moment, the power is on the side of the bitcoin. However, this moment can quickly change and reverse. Governments around the world are looking for more and more ways to begin to investigate trade with bitcoin and to regulate the search for and supply of cryptocurrencies. The reason is obvious - cryptocurrencies, like an anonymous currency, is undoubtedly an ideal means of "laundering money" from the illegal business.
