BTC is in the retreat now, but despite this fact, the change it has made in the market, in economics, finance and banking is simply impossible to evaluate. Thanks to it, blockchain technology has become a topic that has been developed by the largest technological companies. Cryptocurrencies began to be the subject of even legislation (not to mention mass consciousness, mass media and art). Thanks to the success of bitcoin, other cryptocurrencies are developing today. However, I do not recommend investing too much in BTC. This is no longer a game for ordinary players. And these rumors about the price manipulation ... It's better to invest in altcoins - in my opinion. I've invested in the FuturoCoin altcoin (good exchange rate now due to BTC crash) and I hope it will bring me profits.
