Has anyone here ever made money gambling with BTC?
Do you mean the admin of the gambling site or the "player" ? Only a few people has made a lot of money on the gambling the site , but all know that at the end is only a question of luck (and the site will win at 99% of the times).
yes because gambling sites have the slogan "homeowners always wins"
so I always hesitate to make a profit much on gambling sites
