What I love and call a profitable business usually is to hold the coins,or mine and hold the coins during time exactly like ours,a deep crypto winter and sell in the next bull run,it take patience to do this but it is I think a guaranteed trade that will make you profit in the long run.
Holding is profitable and it's proven not just by words but with actuality.
Patience for everybody will determine on how long you're willing to hold and even on the last bull run, we've been too patient and many haven't sold at the top of it because no one knows if that's the peak for bitcoin.
But, that only teaches us and even you're a solid holder still you need to have that point of time that you will have to sell because no matter what the peak goes as it's written that many will miss it.
