$BTC
I've bought 4 BTC for 1200$ back in 2016. The bad news are: Shortly after, I've sold all 4 of them for 2000$, happily cashing in 800$ (which I've thought was quite good at the time...).
Crypto is all about being patient, being informed, believing in your portfolio.
I've learned my lesson since 2016 and here I am now. Waiting for an imminent bullrun and hopefully to get a well deserved return after waiting 8 years.
My two advices for beginners:
1. Never rush into selling
2. Never spend more than what you are willing to lose.
Good luck!
