With the caution that you'll save sime of your investment and or buy back, of course. Otherwise you'll be tremendously missing out on important stuff like this.

no selling. I can get the meaning of your selling bitcoin and then buy it back. what's that for? make some contribution to gas fee? HODL and I promise that you won't regret for it!
any altcoin won't defeat bitcoin.
Dude, you can't just tell him to not sell his hodling lol. If he wants to spend it on something let him do it. Long as he's buying back, there's no point in us prohibiting him to buy.
