The last price drop of the Bitcoin price is very reasonable. As many people have said that it's because of coronavirus pandemic.

The thing is we don't know until when this pandemic will last and the more it takes time, the more people will cash out their assets because they will need more cash.

And what I can conclude so far is people who are struggling with having cash currently will lose their opportunity if the bitcoin price will increase after this pandemic is over because they won't have much money to buyback bitcoin.

So I think it's still not good if you invest your money in Bitcoin even more than 20% right now. Don't gamble on this unclear situation yet and buy Bitcoin when the situation (coronavirus pandemic) is clearly getting better.
But this is pure based on fundamental analysis, not technical.
