Gambling is a reality whether we like it or not. I gamble all of the time. I only gamble with money that I know I can lose without jeopardizing my family livelihood ( paying for food and rent). I can imagine free distribution of money to be a problem for central government as to how to tax that money going through those mechanisms.

Countries that are friendlier to cryptos will attract money and projects into those countries. However those countries need to be stable. Secondly I think cryptos will have to pay some kind of taxes to central government to keep basic functions going.
