So you mean myetherwallet address is enough to receive all kinds of ERC 20 tokens? Don't I need separate addresses?
The answer is simply yes! It's like a built in feature of myetherwallet, you can automatically receive any type of erc 20 tokens. You don't have to set up anything with it, just give your ETH wallet address to the sender and it will be sent to your MEW automatically and once you have receive it already that will appear to your tokens received.
