I don't know about forever, but I'm definitely not seeing a permanent upside limit to BTC's price anytime soon. So there's really no reason to sell any for the time being.
Too early I think. The downwards move is not over yet. Weekly chart gave a short signal to me at 66075.
Just throwing it out there that I'm going to buy $5k more of BTC in a few minutes. If people are stupid enough to sell their BTC because of a new covid variant, I'll be smart enough to buy it from them, that's for sure.
