I still feel that long term investing in bitcoin is too risky. I mean that the thought of the threadrunner have the right to exist but the question of cryptos is still opened. There are some countries which prohibit usage of cryptos, and there are also the countries which support the idea of cryptocurrencies. So, now it is a great financial instrument to trade because of its volatility, but I feel that it is too early to think of investing in it for a long time.
