Well, I'll list some regrets and/or things I would do differently as I remember them...
1 - Since my teenage years, around 2013-14, I had heard about Bitcoin, I even researched it, but back then I thought it was a type of money that only worked on the deep web, although I thought the idea was really cool, due to my other interests,and I ended up ignoring Bitcoin... I only truly understood it by 2015... but at that time I didn't have money to buy it... If I could go back in time (although this would be against the laws of physics, probably generating another version of myself when I went back in time), I'd definitely tell my past self to buy bitcoins or mine and do everything I could to buy even 10 units...
2 - I would go deeper and invest part of the funds (about 30%) in ETH around 2015 and hold it for a long time.
3 - If I were starting to get into this market today, I'd join discussion forums like this one, since the information tends to be as impartial as possible. I wouldn't listen so much to influencers who convince you to invest in shitcoins (like OM) and then only you would get screwed.
4 - I'd adopt my current strategy sooner. Instead of making a single purchase all at once, I'd slip my payment into 3 or 4 parts, so that throughout the week, I can make periodic purchases practicing DCA. I would never have made the mistake of stopping visiting the bitcointalk forum, where many opportunities arise for those who dedicate themselves.
5 - In the beginning, I would talk a lot about Bitcoin to people, but most of the time, I was considered crazy. Today, I talk very little or almost nothing, but unfortunately, people who already know about it keep talking about it. I'd never say that I know about Bitcoin or that I invest in it, as this could pose a threat in the future or people would mock you in the hope that you would lose everything in a bear market.
I think almost everyone here can relate to my answer, that the biggest regret is not having bought BTC when it was cheaper hehehe, preferably in 2013, 2014, 2015...
Another regret I have is that 1 or 2 years ago I didn't spend more time studying about airdrops and new projects, because a lot of people have managed to make a lot of money from this
It's usually at the moment of a downturn that you have to work harder to reap the rewards afterwards
Ohh my friend, this means that airdrops are being profitable for you... I'm happy, someday I should set aside a few hours to research this, although it's difficult to filter and retain what's good, due to the flood of content on the internet.
