So, I'm reading this thread and I see people blaming Mt. Gov trustee, NKorea and Trump for some reason, and other things.
But there could be any number of reasons why the market is crashing that we just don't see. There could really be manipulation going on, or secret deals. Who knows, maybe everyone just decided to stop buying all together because of the tax season coming up. Or there could be a lucrative alternative stock besides crypto that some investors have flocked to. It's all unpredictable.
Take to the market experts to see what you should really do. They're experts at stock trading, and if you're treating crypto like high-volatile stocks then you need to listen to their advice.
Peter Lynch says that you should put down the books and news. He says to buy wisely. In a bear market, he insinuates that one shouldn't look for possible reasons for the crash, but instead, to capitalize on it by buying more from stocks you perceive are going to recover.
So basically, stop trying to calculate, and just go buy into the bear so you can be ecstatic when it turns into a bull.
