Hello, I need more information regarding the Airdrops. I tried to joint one just for to see what exactly is this thing but the requirements were to have a ETH wallet with minimum amount of 0.1ETH. Why is that needed and they can see what I have in my wallet. Maybe it sounds stupid question but that's how we learn. Hope this thread helps to other Newbies like me.
The ICO offering the airdrop must be operating off the Ethereum blockchain, therefore their transactions occur on the Ethereum blockchain and must use the Ethereum wallet.
I'd be careful about these so called airdrops. Most are not actually airdrops. If they ask you to deposit or send Bitcoin, they're a scam or ponzi scheme.
