So a little short brief summary of the nature of bitcoin.
Bitcoin is extremely volatile
Just hold the line and ride it out.
Yeah, it sucks if you bought bitcoin over 10k, but don't sell it and buy it at the rise.
One, you lost a quarter or half of your invest already by selling in the negative, you lose more money due to buying it when it goes up.
That's bad strategy that will leave you with noting .
Just give it time , there rumors that zclassic is joining coinbase( don't know if that's true but what I do know is that bitcoin will rise)
Keep your head up, and if your not affected by bitcoin drops don't waste time and buying shit coins, Buy coins that will prosper as soon as bitcoin goes up(steem)*hint
