The current market is unstable and the recent volatility is increasingly complicating the situation. I think this time should focus solely on investing in Bitcoin and consider investing in long-term coins in order to make the highest profit. Both altcoins are unable to develop and maintain a downward trend this year, so this investment is now very risky and should be avoided. Of course, in 2020, the economy will rebound to be like 2017 again, and you should put your trust in that it will definitely be a time for you to get richer from this sector.
