As others have intimated, you'll never go bankrupt by selling [for a profit] too early. I put $10k into bitcoin when it was $1500, and sold it when it hit $4k. Yeah, I can do the math at $60k and feel bad, but realistically if I had the mentality to hold it from $1500 to $60k I would have waited for it to hit $80k and I'd feel objectively worse today about those paper losses, albeit with a little bit more money in the bank.

At the end of the day doubling your money is exceedingly rare, especially on any single security, no sense feeling bad you didn't 10x it.
