look at the history of litecoin, it began to grow only after bitcoin returned from 200 to 1000. More than bitcoin grew only new coins such as DASH at that time. Now the new coins are BTT and BSV, so I bought BSV
Now, it will be a hard task, but I will try. As I see the situation, OmiseGO, Waves and Stellar can be the best gainers this time. Probably, they can even increase in 3 times. Ethereum will go up also.
1) these coins fell heavily, the price may never return
2) Altcoins will disappear because bitcoin can do anything and they do not make sense. Only BSV will remain because this is the version of bitcoin with a large block that is needed
