What is your exorbitant lesson investing in crypto last bull market (2021-2022)? I will like to share mine...
1. I watch YouTube videos of people gambling on meme coins with just 100$ and making thousands of dollars, I did the same and I ended up with tokens that I can't sell on an exchange, buying works but not selling.
2. Friends told me that Vitalik have promised Proof of Stake on Ethereum for years and it never came to past, I believe them and invested in Eth mining equipment, I am now selling to gamers since they are not profitable, not even a bit.
3. 100k per BTC nearly brainwashed me, I escaped this though but I really believed it, if I had some funds at the time I might have invested on BTC at ATH, thinking its going to 100k.
Those are a lot of lessons you needed to learn but while you may feel like the losses are too great, believe me when I say to you that this is not rare at all and there are many people which made way bigger mistakes than you.
In my case probably the only mistake I made during this bull run was to not invest more in bitcoin after its crash on March of 2020, but I do not think too much about it as no one knew how bad things will get due to the pandemic, so it is a mistake I can easily let go.
