Since the nature of these two topics, the audience taking part in these two markets and the potential to earn and lose, i do believe these two, Bitcoin and Gambling are just the perfect match
Bitcoin can go with any online payment service, not just gambling.
Yes I agree, however I would like to say this that base on my observation most of the users of bitcoin is from the gambling industry. This gambling and bitcoin plays hand in hand to improve their industries both the gambling and the crypto currency industry.
