Considering the AI based projects to be short term is not a good advise because we are already in an era of Artificial intelligence booming into everything, and besides, not every AI project survive through the storm of pump and dump. The ones mostly acceptable by many or widely used internationally are really the ones listed on many major exchange like Binance, coinbase, okex, Bybit and many others. These ones have a big purpose of integrating more features into the ecosystem bringing new innovations into it. These you mentioned are AGIX, and the rest.
Memecoin should be used only for short term, purely short term, nothing much.
