That is everyone's face buying any amount of BTC over the past few months.
Internal dialog of just about eveyone: BTC is going up, better buy more. Wait, what if it goes back down again? But it could keep going up. but it also could drop right after I buy. Its probably going up though. Ill just buys some. Wait, do I really want to buy it right now. I am sure its fine. but what if it's not...
That should sum up everyone's thoughts lately.
