Hahahahaha I was up all night watching the Bitcoin and Ethereum charts and this drop was pretty scary indeed.
But that is the exact reason I don't like Bitcoin and trading it. The market is too heavily manipulated it's disgusting to me. Out of the blues the markets booms or crashes. In a way it doesn't follow TA at all. It's crazy at times lol
If you just HODL and pick a target price, the drops aren't much to worry about. Keep this in mind, bitcoin has never not made a new all time high... Let that sink in.
