Most of us go to coinmarketcap when we search for altcoins, but there's allot of unlisted altcoins. What do you think is the best altcoins that are not listed on coinmarketcap?
the only coins that are not listed in anywhere are either too bad coins which were scam, virus, or any other bad reason and these lists removed them to protect users. or they were dead coins with no longer active blockchain.
this group are obviously all bad coins.
also there are very new coins that are not yet released, so these sites like coinmarketcap don't list them. again saying anything about if they are good or bad is too soon!
also remember that when opening the home page you only see a limited number of coins you have to go to the next page to see the rest of them!
