Thank you for the article. There are a lot of scams out there. From free airdrops to fake ICOs. One really needs to be careful about these. If one wants to apply to these airdrops then I think the best way is to not send any crypto to any address. Also, for the ICO's confirming the contract address in all different platforms of the project would be the best way to go.
