People who got into crypto around BTC all time high in 2021 bull run, what has been your best & worst trade/investment & what have you learned so far?

I got into crypto around March-April 2021. In April BTC hit 64k. During that time I mostly bought small amounts of BTC, ETH, monero, Z-cash, Algo and few others that were in the top 100 coins.

I sold some of them at a loss & I am still holding some in the red.

My best investment was buying a coin called SFUND around 0.7$ in July or August of 2021, within 3-4 months it went upto ~16$. This has also been my worst trade since I only sold enough to get my initial investment out, but didn't cash in on the 22x profit. I was too lost in the hopium & dreaming of 50-100x return. I still hold it till this date & it's back at 0.7$. It might pump in the future but I don't think it'll go more than 4-5x, since its supply has increased & will keep increasing.

The lesson I've learned is that every investment is a game of hot potato and you must cash in on profits, 99% of people don't care about the tech (Including me), it doesn't matter if it's a meme coin or a solid project or BTC or ETH, we're all just hoping that we're buying at a decent enough price to profitably unload the bags on the next generation of people who get into crypto in the next bull run. People hating on FIAT money is the biggest bs in the crypto space, at the end of the day people in this space are exchanging their FIAT to get more FIAT in the future, they're not doing it because they genuinely want to use crypto.
