I have never sold any BTC. Keep in mind that I have never bought any crypto either - all the crypto I have has been clients paying me in crypto for services rendered.
Don't regret hodling, but woulda been cool to buy something like this at the height of BTC end of 2017, for btc

Part of the reason I have never sold is that it's too hard to sell a lot of bitcoin, all these U.S. wallets have limitations on how much you may sell at a time, and then also they want to report your transaction to the US treasury department. My main wallet where I have most of my BTC is overseas and has no mechanism to sell for US residents, so I'd have to transfer it to my US wallet just to sell.
But if I'd traded it for a second home, no selling limitation issues, no reporting (I don't think). So something like that if it comes available again when BTC is back above $20K, I might go for.
Another possibility when BTC is over $20K would be that I sell the wallet intact to some whale, but the sums involved would not make it so easy. Not like meeting a guy at Starbucks to sell a few hundred or even few thousand dollars in BTC for cash....
Over $20K is the minimum price at which I would even consider unloading BTC. Given that it was once just below that, I'd personally never consider selling below where it once was.
Meantime, anyone who wishes to pay me in BTC, which I continue to receive some weekly lately, bring 'em! I shall HODL.
