After seeing the current rally I would never sell Bitcoin below $80k but I will check the market fully before even selling at $80k because if the market become overly bullish during $80k price then I will wait for the pump to reach its intensity before selling some of my holdings.
Bitcoin may get to $100000 in this year. I think selling at $80000 will only selling too early. Although people will have different options on this. Anyone that should sell market should sell around $100000. Bitcoin is going above $100000.
I would most probably sell it for the purpose of trading not for permanent selling at that price. I'll accumulate more Bitcoin with the money when it sees a correction, that's how I'm planning to sell Bitcoin. I guess if you really wanted to earn some good profits then don't sell but hold your Bitcoin, however if you're good at trading then you can sell and rebuy in order to accumulate more of it.
Some people will see it as a correction but before they will know after they want the market to dip further, they will see the price higher than the price that they sell it. That is one thing about trading.
