i was now for a few month "offline" and i want to buy some new coins.
My last knowledge is, that yobit and bittrex are adding new coins,
but are there any new popular exchanges who are adding new coins?
If you are asking for about where you gonna buy the other coins for a newbie member here, I would suggest you to go in nova exchange, or you can also try in cryptopia or and alcurex. Those exchange are really good for a beginner when you are doing trade for the altcoins.
