Do you mean projects where you pretty much consider it as a lost investment or gambling? I don't know about that negative attitude about Doge and Shiba. Sure they're meme coins that don't have insane growth anymore but I don't think they could crash to zero and lose all of your investment.
I mean, I consider it speculation rather than investment. Do you have any proof that meme coins like doge and shiba will never go away? I agree with you that they are backed by a large community and their market cap is larger than many other potential altcoins. But in cryptocurrencies there is no such thing as 100% certainty,
even tokens with utility and usecase can disappear but for doge and shiba it is nothing.
