I guess ethereum is finding its resistance again after surviving a long run in $200, I think it will drop to $220 then finish the whole year above $400. Don't mind the short drops of it, ethereum always does that.

The whole crypto is volatile. At the moment, the advantage of ETH is that it has an active roadmap, so I assume its growth is more confident compared to other cryptocurrencies. Good market conditions will help ETH, but even without it, if the roadmap is successfully implemented, ETH will grow. The only thing that can radically affect this is the global economic crisis, which unfortunately is actively developing.
