That is what scammers have been doing since 2010, create new coins from thin air then market them and then dump them prior bullrun ends, repeat next cycle. The coins you mentioned I remember them in 2018, I have not heard about them this cycle around.
Yes apperantly there is some scam coins, and others just fails. But Zclassic I was chocked about, it had a ATH value about $200 back in 2018, then it just dumped all the way to the bottom. I mined a lot of them with my ASIC Bitmain Z9 Mini, it was the most profitable to mine on it, never ROIed because of that
Also SnowGem, I really liked it, had a nice wallet and webpage. One day when I checked CoinMarketCap it was just gone
