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 tokens usually use ERC20 token and you can use myetherwallet to stored your tokens from the bounty campaign. You also can trade your tokens from the bounty into bitcoins or other cryptocurrency too, but you need to wait until the tokens get listed on exchange. Sometimes it takes many months to wait until the token listed on exchange.
