Can you tell me what coins myetherwallet supports? I have an account there but i saw there is only ETH.
Do you see the button that says "Load tokens"? Click it and you should see a long list of tokens added by MEW. If a token isn't listed, you can "Add Custom Token" by inputting the contract address, symbol and decimals of the token. This works for any ERC-20 token. Any of the ICO tokens listed on Shapeshift, like SALT or Civic Token or Basic Attention Token, are compatible with MEW. Any time I buy tokens for speculation, that's where I store them.
If you want to trade fiat without ID, use Localbitcoins.
Depending where you live, this may not be possible anymore. I'm in the US, and the high volume traders on Localbitcoins seems to require ID now. It's definitely easier to use an exchange that doesn't require KYC.
