Ughh, fuck, I was wrong
9999 combinations x 9999
You're right
Sorry
Wow, that is hard to hit!
Even if it was 1 : million it would need to be over 160
BTC to be profitable
So this way it would need to be 16 000
BTC 
Hmm, that doesn't sound right.
My back of the envelope calculations is anything >1000
BTC. Each bet you have 1 in 10 million chance of winning the jackpot. To qualify for the jackpot you have to "spend" 0.0001 BTC in EV. So I think you can model it as approximately:
(1 / 1e7) * jackpot - 0.0001 = 0 which gives you
jackpot = 1000 to be 0EV, and thus everything above that "profitable"
