Am just curious what is the wallet address for? Is it for payment? If yes why not wait for a winner to be selected then you can ask them(the winners for their bitcoin wallet address). I can see no details needed but it's ironic that the most important detail(wallet address is needed so early)
I saw that it was an initial form to get free like a faucet which would then be randomized. This him word .
Free Cryptocurrency Lottery
just enter your BTC / ETH / BCH Wallet address and you can win a random amount of cryptocurrency!
if someone wins, it will automatically enter to his wallet. By the way His project is very good but only generous people will continue the mission, I often see such things but have never received free crypto in them. I would not have guessed before there was evidence, I would like to see the development of the project released.
