Counterparty uses Bitcoin like Etherium uses Gas, its about $2 worth of Bitcoin to send to the swap, by the way the Dev is paying for the Eth on the other end to send to your ERC-20 Address
By the way, what are the transaction fees on Eth? $0.12? Wasn't it the dev's bad desicion to use counterparty - so shouldn't he be debited for the swap?
It is not bad for the devs if some Covals are burnt because they are not swaped. Less supply of ERC-20-Covals means that devs have a better chance to cash out, finally.
Just ignorant.
