Hi Andrey123,
I understand you perfectly. I operated forex and indices with Futures and CFDs, and it is impossible to know what the price will do in the future.
But in most cases a good technical analysis can help us make a successful trading.
I think that Bitcoin and cryptocurrencies are generally very undervalued. I think this year they will grow a lot, and this crisis at the beginning of the year creates a great opportunity to ride the big wave of cryptocurrencies this 2018.
I appreciate your advice. You always have to be alert when the market changes its main trend.
Gustavo.
