Interesting question, I know. For me personally the answer is no - I have not ever regretted having gotten into bitcoin, despite having spent hundreds and hundreds of hours researching the topic. It's always been an interesting ride.
But I have a friend who got scammed and he regrets having had anything to do with crypto in the first place. It's pretty sad but there's nothing I can do about it. I even offered giving him half of the amount he lost from my own crypto stash (mind you I am not rich) but he's so scared that he's not interested any longer...
Me too. whenever I invest in something, I will never regret for my investment. The reason is quite simple, I already did some researches about my investment before investing, that is the reason why i am so confident with my decision.
I too. I made mistakes, it did not bypass me, but I continue to experience this market and try to make a profit. Because I know that other people successfully use it, so why can't I?
