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.
In my opinion, sure that you join the ICO bounty project, I suggest you using mobile app name sFomo, this app helps you tracking the newest cryptos are indexed in the exchange floors. With the app, you can update the newest altcoins and ICO.
