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?
Some ICOS launch their own blockchain & they distribute token on their exchanges, so you have to make an account on relevant exchange to get tokens, you can trade your tokens there for bitcoin or ethereum as well.
But mostly ICOS uses ERC20 for token distribution, for that you have to make an account on MEW. You will receive your token in MEW after that you can transfer tokens to their proper exchange for trading.
