Even if you're right, holding a short position is very expensive. It's all about timing. also, there are not a lot of vehicles to short depending on which jurisdiction you live in, especially for retail investors. simply telling somebody to short Bitcoin because of their thesis is showing your naivete and lack of trading experience

 90% +  Bitcoin long exposure. I also use options to generate income. no gambling or guess directionality/timing. simply using traditional financial markets to take advantage of mis pricings in Bitcoin derivative markets while I still can. eight years strong, slowly starting to narrow as institutions are starting to catch on. 

I've never once tried to trade a chart. never will.
