In fact, the biggest mistake I just made was, selling all of the Ethereum I owned for under $ 700. Well, to be honest it's late 2020, and I truly believe that Ethereum prices could be even higher. however, being affected by FOMO, etc., I sold my assets. Even though I feel it's a pretty big gain, I'm still sorry when I see the current price.
Nobody's perfect. Everyone can make mistakes every once in a while. Just move on and keep moving forward. Monetary losses are unavoidable, especially in crypto land where prices are extremely volatile. I've lost many opportunities to make profit with crypto, when prices went all the way to the moon in 2017. Fortunately, the bull market repeated itself, allowing me to take advantage of Bitcoin's price gains. With an ATH of $32k per coin, my gains were greater than they were a couple of years ago. Still, I've lost a lot of money during crypto's early days when cloud mining was overhyped. One of my biggest mistakes was investing into GAW Miners' "hashlets". Little did I know that the whole operation was a scam. Thousands of dollars were lost when GAW Miners' Josh Garza decided to run away with the money. I've also lost money when going all in Paycoin. GAW Miners claimed the coin will always be worth $20, only to go down the drain a year later. At least, I've learned a valuable lesson. And that is to never invest more than you're willing to lose.
Nonetheless, crypto has many risks than Fiat due to its widely volatile and unpredictable nature. You could either end up being rich or poor in an instant. As long as you cash out your crypto every once in a while, you'll be able to stay safe in this wild and crazy world of crypto.
