Let me get this right:

Your "winning strategy":

• only works on a specific site
• nothing to do with martingale
• it is possible to loose
• you can ask for your money back
• you have played it 10+ times
• you earn 2-3 bitcoins a day

Your "system"

• you may post a tutorial if someone is interested
• even better, a video tutorial
• system is not for sale
• you don't want to post it publicly

How am I doing so far?

EDIT: OP offered a link to youtube. Will see what happens next.
