When I saw the prices of crypto currencies there is almost every coin's price fell upto 20%.Do you think this is just happening due to South Korea's ban over crypto currencies or there is other reasons for that.
I hope the condition will be back normal soon but I am worried a lot.

I don't think there's a reason behind this "correction", that's why I think we shouldn't sell here. It might be a bull trap before another megatrain to $20K and above!

Seriously though, this is the biggest unrealized loss I experienced in 2018 so far and I totally never saw this coming. Too bad I already spend my spare USD and BTC few days ago for altcoin shopping ... right before the crash happen huh.
