4.Bitcoin: Interesting, but risky
In cryptology you need to invest carefully.The market is speculative, can sharply grow and fall. In 2017, bitcoin cost about 19,000 dollars, now - about 8 thousand dollars. Intraday fluctuations of the Crypto-currency may be 25%. You need to have iron nerves to withstand the jumps, because you can lose everything.At the same time, how much will Bitkoin cost at the end of 2018, it is unknown, because all bold forecasts have come true. But one should not think that cryptography is a costly investment.
Therefore, the choice is up to you as always.
