Can someone recommend a site to start trading altcoins? I'm looking for one that is trusted and has a good variety of coins.
I'd recommend you the yobit website, their aupport ia a little bad but they have a ton of alt-coins and adding new one as soon as they are published/announced. There may be some other webaited but I know about this one that has a vast variety of alt-coins.
Yobit is not good to use due to many users are complain at their poor service. It takes a lot of time to respond. Also its not good for newbies because its not user friendly. poliniex and cryptopia are good trading sites. You should try there.
This is true. As what I see yobit have too much coins that are probably just made so developer can make money. Poloniex is number one in altcoin trading and coins there looks legit.
