Altcoin/Platform for starting survey?

[Floors]

Does someone know a possibility to start a survey for people that are familar with Cryptocurrencies?
The people that are taking part on this survey should get a reward (cryptocurrency) for their effort.
The only problem is, that I need legit data, not generated by a bot to gain tons of rewards. Does anyone know any pretty safe solution to get real data? Maybe there is already a working altcoin with this function running.
And for sure there should be some hundreds of active users.
