It looks like your addicted to gambling but doesn't have money to play these games so come up with this kind of offer to full-fill your gambling addiction right?
No strategies will work in gambling and only win situation will be for you not for the people who will pay money for this service.
Check out my signed wallet addresses, all funds are intact. I have not an addiction, but a skill.
As for "no strategies will work in gambling" - this does not apply to someone who was intimate with the dev who owns the gambling site, and thus has some insider information.
I'll elaborate further:
The site in question uses an interesting system to rope in users. For each new user, it will let them get a certain amount of profit with ease (the house edge is significantly lower), and once this quota is hit, they will start losing. This way, people feel like the game is not rigged and even upon losing it all, they'll keep trying to put in more money. What I do is, I play until the quota is almost hit, and then I cash out. I then change my MAC address using a spoofer, and use a VPN to change my IP. I also wipe browser metadata and cookies, and restart. Next time I'd suggest you not to make remarks about things you know nothing about.
I don't fully agree with your concept because it is just your imagination. If site implemented a probably fair system then they can do like what you explained in above post unless you choose to gamble on not fair site.
I didn't see anywhere your signed message and also it will not prove that you're not addicted to gambling because you can use other address to gamble.
