I used my wallet adress, on which i have 30 + eth, and when it came to passing, i just got a message that my thing is empty.. I tried replacing to miner wallet address but it was too late, you guys called no on such mistakes. I am a bit of a newb, so bare with me

Have you read the description of the form?
"Your ETHF (Ethereum Future, not ETH) wallet address. You MUST HAVE 30 ETHF or more on THIS ETHF ADDRESS.
Please, check your address by blockexplorer before filling this form"
