Considering most of the market is down 70-80%, this coin/token would need to have fallen a lot harder than most and/or performed worse than most on the way up during the bull run, or might’ve had bad news that’s given it a poor reputation and may negatively impact it in the longer-term.
Mine I think would have to be XLM. One of the few cryptos not to hit a new ath in the recent bull run. Such a disappointment. Seems like a lot of the 2017 coins performed similarly underwhelmingly, especially the payment coins.
