I really don't get the mindset of all these people saying hodl 100% of the time. It is quite clearly more profitably to sell when the market is down, and rebuy when the market is up.
If you do that several times in a row you will end up with significantly more BTC than when you started with. Obviously this larger stack will then be worth a whole lot more if BTC ever reaches the moon as so many proclaim.
You could even throw in some shorting on the downturns and prediction markets for the upturns to increase your profits even further.
Mindlessly holding is now the way for a trader.
