Crypto that you regret buying.

So, guys just wanna ask what is the one crypto that you regret buying and what is the reason for it?? For me it's definitely celr i am not calling it a shitcoin but i bought it when it was at an ath cause my dumbass believed that it was gonna reach 1$ soon. Also i guess if you are commenting you should be ready to be downvoted by the fanatic
