I am using many myetherwallets to save tokens. I want to transfer all tokens to one only wallet. But I have only ETH in one wallets, other wallets doesn't have. How the best way can I tranfers it??
The only thing you can do is to transfer small amount of $ETH (around 0.000x value in $ETH) to all wallets and then transfer your tokens to the intended wallet you want to send.
There is no other possible way to do it. Eventually, when you are done in token transfers, you should transfer your remaining ETH from all wallets to same wallet.
