I really need to sell some altcoins, but the site I used to use isn't working anymore (No clue why). The two major coins I need to sell are Bitcoin cash and Gulden. If anyone happens to know a good site or multiple sites to sell these coins, please let me know.
You can sell Gulden and Bitcoin Cash on bittrex since they are both listed there according to coinmarketcap. You can also sell other altcoins there but maybe some of what you are planning to sell ain't listed there. If possible list the other altcoins that you would like to sell for others to determine what exchange is good and convenient for you to use. If you don't want to list them here one by one, you can figure it out yourself using coinmarketcap.
I've tried using bittrex before but never really had succes on the site. They denied the first profile verification so they asked me to send a picture of my passport, I did so, and that got denied aswell. Thanks for the suggestion though. cheers
