Just wanted to ask if we need any kind of wallets to recieve those tokens after the completion of campaign.And also how can token be traded into bitcoins or other cryptocurrencies.Any idea?
The kinds of wallets that are needed to receive the payments from the bounty campaigns are usually specified in the campaign thread. Most of them are build on the ethereum platform so they require ether wallets and they ask you to provide an ether wallet. but if it is a coin that has its own wallet then they would specify it and tell you where to get the wallet from.
