Which cryptocurrency have you completely lost faith in?

As the title suggests, I'm curious about the coins that have led you to lose faith in them and the reasons behind it. Did you buy them at a high price without sufficient fundamentals? Were you disappointed by the project's leadership and core team abandoning it? Or did you get involved in a pump and dump scheme that resulted in a severe crash?

Given the current bear market and the substantial outflow of funds from the crypto market, it's understandable that you might have some regrets about your purchases for various reasons. However, considering the likelihood of another bull market eventually happening, which of the cryptocurrencies you bought do you believe is the least likely to make a significant recovery?
