That's right, right now, when the price of bitcoin is in such a big decline. If it were me, I'd buy it!
I'm investor, but actually maybe a gambler. 
Because bought bitcoin not with analysis but with something like this, event or news or any condition and don't know what will happen or maybe just guess without any analysis. I think it can be considered gambling to me.This is not gambling because you have basis before you buy Bitcoin. Gambling is buying random coin without giving a shit on both fundamental and Technical analysis. Events and News are both a fundamental analysis which you are not aware though. All good if you are buying Bitcoin for now. Only future trading is the gambling when you are buying Bitcoin.
