What crypto do you regret buying/not buying?

What crypto do you regret buying or not buying? Looking for some opinions or even personal stories here!

There are a lot of crypto currencies that I missed since the beginning because of a kind of bearish mindset… I kind of regret investing in SHIB coin once because I got hit by the FOMO thinking it would reach the 1$ price for each coin, unfortunately I was till new crypto and had no idea what the total supply and the personal supply was and that it wouldn’t go higher because of that…

But anyways I’m looking forward to hearing your stories!
