a few days ago ethereum experienced a drastic decline. and it turns out it's currently under $ 200! My personal predictions are wrong, and may not be true. what's the next step?

I think vacationing is a good idea while enjoying a vacation !!
Lol it's unpredictable market... Nobody knows where this going. Although in the other side, this is the best time to buy ethereum while in lower price and take a vacation. This can recover soon and I still believe in this currency to become huge in the future.
