Thank you man... I really hate scams... they are the plague of this wonderful world.... unfortunately it's not so easy to find if an airdrop is a scam.. so thank you for your effort!
I'm very curious about the new POLONIEX now that Circle bought it.... this can really become the most reliable exchange of 2018. I like also binance and bittrex. The best one for using also FIAT Money (€) in my opinion is still Kraken...
