Great work there buddy!
Went super smooth this intervention

I would also like to present myself for Alpha-testing.
I'm a student in applied technologie.
Debugging and tracking bugs we do on daily basis
If something ever needs to be tested before putting it online, always welcome to contact me

EDIT:
I just saw this suggestion:
"Can you make option for user to transfer btc to another user ? We can help promote this site and do many giveaway by that"

I would strongly recommend you from refraining to add this option.
Seeing that you already have a problem with multi-accounts.
This will only provide those who want to gain btc like that to try even harder, and they will always succeed.
If I could vote, I would say no to this.

@Fildza
If you want to do those giveaways.
Get cashed-out first and use that to present you giveaways
