No one ever told that altcoins are dead..

Altcoins are great! Thing is that biggest part of all alts are scam, coins without product or just shitcoins.
But to say that alts are dead it is ridiculous.

But all that comes out of the top 100 can be said dead , very few of them are developing , for a long investment is still difficult to find the alktoin that fit
There are fully pointless Bitcoin Gold, Ethereum Classic, Bitcoin SV and Dogecoin in the top 30 as for now. About what top 100 are you talking my friend?
