I'm not speak about how to hack bitcoin, in the my opinion the option using bitcoin as payment system is still very risk. I still have not know what the reason it. as example : microsoft accept bitcoin as payment system, what it is for all countries? ;;; usd tether is currency based USD, what does I can register in wallet.tether.to directly with my original IP? (sorry, I'm not USA/UK people)
my question is, why just for certain countries only?
other example, in the last year I can enjoy VPS service from vultr.com using bitcoin as payment system. but now they stop bitcoin payments to people who have just signed up.

I'm not sure if Google Play accepts Bitcoin or not but I'm looking into it.
