I've shorted bitcoin since it went below $10000 with my entire life savings. I've even thrown in a bit of CFDs for good measure. At the moment, I'm up ~$40000 on CFDs alone. If Bitcoin even hits $2000 this year, I'll be able to retire to my dream country: Monaco. Apparently, the word is that Bitcoin could decline as much as 90% from it's current peak.
You need to read The Rules by Larry Hite before you go bankrupt. Also, you may be on the wrong forum, try wallstreetbets on reditt.
You're dumb and you will go broke. The trade of the century is not shorting Bitcoin. It was buying bitcoin at $1 and selling at $20K.
I think it's cute you think a 20% drop in bitcoin is somehow special & not as likely to go the opposite way.
You can rebalance in a down trend to achieve far more than 100% potential. Especially, if Bitcoin goes from $20K to $1 you can do the same in reverse... Of course, when (not if) Bitcoin starts one of its bull moves that will flatten you if you're sitting on a leveraged short. OP may actually be smart and putting on a single high conviction trade that will let him retire, but that depends entirely on how his exit plan looks like. If it just is "hold until Bitcoin hits $2000" his chance of success is far more limited.
