The industry is already more than ten years old and it's a very old concept to make money through mining Cryptocurrency, they should accept trading, investing and even bounty hunting as a source of income from Cryptocurrency, casinos I'm playing have not asked me yet a full detailed of my source of income, I think casinos should include in their terms what means of income in Cryptocurrency they are accepting, its injustice for players who play with their income coming from trading, selling services because these are already legal ways to make money in Cryptocurrency industry.
