I will be sending my ethereum from myetherwallet (an erc compatible wallet).
I wanted to know do we have to send ethereum from the same wallet (that we put the public address for, in step 2?)
Or do we use that wallet (which was put in the step 2 guideline) to only accept power tokens?
and i can instead send my ether in myetherwallet from my other account which holds my ether currently?
Basically does it matter which wallet i use to send ether as long as i use myetherwallet?
Myetherwallet supports all tokens so I don't know what exactly you mean. There is no particular wallet at mew that supports tokens only. It's the same ether address that can be used to receive ethereum that is used to receive tokens. Just that
