Just like some have already said, my greatest regrets is not buying bitcoin at the early stages. I think back then I knew what it was but don't trust any thing online so I literally just focus on better things and tried not ruining my plans for the future. Until now, I wish I could have a time machine and go back to buy some BTC when it was just $1... I guess so many people missed that opportunity or some knew of it's existence but threw away the opportunity...
Exactly, this has been most people regrets in the journey of crypto.
When they introduced crypto in the early days, people rejected it, and those who even accepted it, did not take it serious, because they all think that its a scam, so no need to more effort in it. Though its not actually their fault, because the awareness has not be spread out as of then, and also the way corruption is increasing each day, people will hardly believe what one is telling them, especially in investing on what they can see or touch is very challenging but thank God, the knowledge is now widely spread now and has always be of help to most people.
