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?
Bounty campaign usually accept Ethereum ERC-20 wallet like myetherwallet, so you can use it to receive the tokens from the bounty. To trade the token you must wait until the token listed on exchange, sometimes it takes a long time to get the token listed or you can check it on coinmarketcap, is the token listed on exchange or not.
