I'm an Ethereum noob and I recently participated in some of these ERC20 token airdrops. I'm using MEW and I've never sent tokens before. There's no ETH in my wallet, and I need to send some to cover the gas for sending the tokens. MEW says an ETH transaction is 21000 gas (which I've had no issues with in the past) and a token transaction is 210000 gas. How much ETH should I send to cover say, one transaction? Can I send several different tokens at once? For example, if I wanted to send all the tokens to EtherDelta...
Thanks in advance!
