Which crypto exchange and use for tokens? (ERC-20 standard)
IDEX - almost any popular ERC20 token is there and because is decentralised exchange, you do not need to make any verification or pay takes like 0.01ETH on withdraw.
The oldest DEX where you could trade by any contact address is EtherDelta.
If you need liquidity, I could recommend you both Kucoin and Binance. Both are for tokens/coins in Top 200.
