It was 2-3 years ago if I remember. Crex24 was flooded with coins and price dumped like 99%
Some people bought coins at that low prices (all down to 2 sats). Later, developer offered everyone to sell again that bought coins at current price in order to burn them, but most of people didn't want to sell their coins, so coin simply died. This told you how "serious" project was. BTW, I liked coin. It had small supply, which I considered to be good.
