The worst advice and I regret it until now is, when my friend from abroad suggested buying 1 or 2 Bitcoins in 2020, when the price is $6000, wait 1 or 2 years, that's the worst advice for me, because I didn't buy and I regret it.

So, for now I'm not going to ignore my friend's advice anymore and I have to do it, not wanting any further advice about Bitcoin to get any worse and worse.

My friend suggested good, but bad for me because of my selfishness and distrust, that's what happened.
