What important lesson did you learn about Crypto in 2021?

Been a year full of Crypto surprises, from crashes to Rugpulls to so many Memecoins getting in the top 20. A lot of people lost a lot on these coins and learned their lesson, some still are thinking about it, and a lot more will keep losing that way but have what have you learned that makes you a better investor this?

Maybe you hadn't expected the crashes and now you're better at holding, or maybe you don't FOMO anymore seeing how risky those coins are that go down as easily as they go up. We did see 69K BTC this year as well and ETH also performed very well so they're still the safest and best options in my opinion.

And all the predictions saying 100K BTC and many others turned out to be false of course, everyone's just speculating with nothing to back their claims and a lot of people fall for it.
