I regret not buying more in the past few weeks when it was near 65k. But right now I can sell covered calls with 280day expiration at 10% premium to current price yielding 14% to current price. So if it executes I make 24% in 1 year and hopefully it drops again in the future. With a company like tsla or nvda that have similar yields if it executes u probably missed out on 2x profit and if it expires they may be in permanent decline.
But you really only win if bitcoin fails to go up at least 20% per year. Then you get to keep doing it without selling. If bitcoin doubles you missed out. Which is why I may want to wait until it hits at least 100k before selling cc.
