I mean, you'll just die out and still waiting for bitcoin to increase in value? Of course the value of bitcoin will definitely continue to grow but there'd be no point if you're not going to use them.
You have to sell it on a moment and that is also the moment when you are getting profit or not.
If you do day trading, then it is better to sell if you make some profit. I don't have a ability to do trading, so I will hold it for the long term.
Today's price is already taking into consideration the halving.
Only a fool would think that on the day of the halving the price will spike because less BTC are produced.
I would love to be proven wrong, that would be great !!!
