Hello, my theory is, that another strong run on cryptocurrencies can start, when stock market, which is pretty overheating starts falling. In that time will be Bitcoin pretty low. I think, that we are still not at the bottom. This stock crash could happen even in 2019. Literraly no one could tell what will happen, but as i invested lot in altcoins, i hope it will recover, but i dont expect it will be soon.
