selling. my very first buy was 0.6 btc for $60. i sold it for about $75, and thought myself pretty savvy for making a nice little profit.
when i finally got into it in earnest i took me a long time, and a hell of a lot more than $60, to get back to that original stack.
i did learn my lesson though, haven't sold a sat since then. never dabbled in shitcoins, or staking, or leverage, but i still cringe when i think about my one and only sale
