Gate.io and Poloniex have listed a new generation of meme coins, including Doge 2.0, Shiba Inu 2.0, and Pepe 2.0. However, the communities behind the original meme coins being copied are not thrilled about the newcomers' appearance on the scene. The rapid rise and fall of the meme coin 2.0 economy may suggest that the craze was just a flash in the pan. Meme coin traders are notoriously fickle and even seasoned traders need to be careful in a world where assets can increase their value tenfold or more in a single day but then lose it just as quickly.
