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.
just see the newly registered coin, for example binance announces that it will register a new coin and you can see it, I think if the coin that will be registered in binance is a good coin for an old or new project depending on the agreement they register the coin
