Hello,
Most of the people join in bounty or airdrop and earn tokens. Even I also. But I don't know where I can sell that tokens with ICO price. Can anybody suggest me any site? Really I'm facing problems for this token sell.
Indeed an airdrop tokens from ICO usually dont have market/exchange yet.
You can monitoring in their community channel about their exchange or plan new exchange list.
Or you can track their tokens in
https://coinmarketcap.com for their exchange list, only if your ICO already listing in coinmarketcap.
