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?
ERC20 tokens wallet must be a common wallet amongs bounty campaign, MEW is the best choice i think. But sometimes some ICO project had their own wallet but you can withdraw your reward tokens to your MEW after they distribute the rewards.
You can only trade those tokens to another crypto once they got listed on an exchanger.
