Made MVP and simple landing page. Need your advice what to improve!

Hello from a newbie indie hacker!

Recently I thought about brute forcing Bitcoin’s private keys and came up with idea that I could make such a service for everyone. A user signs up and I’ll use his id as a seed for individual brute force worker (a sieve) querying random-generated Bitcoin keys. If the service find a private key of the account containing any funds, it will send that key to the user, which seed made that correct guess. It is highly unlikely (10^-60 -ish) the service will gather anything but on the other hand it’s free for the user! They only need to provide their email address and hope for luck.

I made quick and dirty prototype for this and created simple (and lame!) landing page: https://sievechain.com

Now I’m struggling what to do next - how to promote it, how to attract first users.

Will appreciate any advices and critique from the community!

Thank you in advance! Sergey.

    Hmm, does this effectively steal bitcoin from people who are unlucky enough to have their keys guessed?

      I wouldn't call it "steal", but you got the idea correctly!

        While I will admit that I'm not well-versed in crypto, it's hard for me to imagine many people agreeing with your belief that this is not effectively stealing bitcoin. The keys are long and complex as a security measure to prevent guessing, no? How is this different from guessing the combination to somebody's lock, the code to their safe, or the location of their hidden house key?

    Save the electricity and try something else
