How does one know which altcoins come out recently and thus are trading pretty good? You can check coinmarketcap to see which coin has increased in price or decreased in price the most in last 24 hours or 7 days or month etc. But besides that, are there sites that show what coins will be released soon to the public? Thus by that i mean being able to buy from exchange like binance etc.
to find out which coin-coin will be released to the public soon, please search for a number of places like Icobench and Icorate and many other sites that can display various coins that will be released ... in coinmarketcap we can only see coins that have been registered at various markets then with the coinmarketcap we can find out the movements of each coin that is there ..
Icobench and icorate are crap sites and forget it because most of the scam projects are being listed on there, CMC needs some requirements and that will be only listed a coin that already traded in some exchange sites that have already supported by CMC
