Do not regret it my friend, DOGE just got lucky and basically won the lottery in luck, and a bunch of kids on TikTok made it a lame fad for a while. It has always been a bad investment, and you were right to sell it, your decision was correct.
Poker players often tell each other a wise saying: "dont be results oriented". It means that you shouldnt beat yourself up over taking a loss after making a correct decision. If there was a decision that you knew would make you win money 99% of the time and you went ahead and did it, but you just ended up having some bad luck and that time happened to be the 1% of the time that you lose, it doesnt mean it was the wrong decision just because you happened to lose that one time...it was still the correct move regardless.
Hope that makes sense.
Cheers
