I prefer to immediately change the bounty to BTC / ETH, but this is just my idea. if one believes thet have participated in an interesting project bounty, he does well to hold
It is better to keep our tokens in our wallet if the number of btc / eth we get isn't good enough after the conversion process. Some projects are still running today and who knows one of our tokens will give us a big surprise someday. Hold is the only way we can choose to deal with worthless tokens to this day.
