look,btc casinos investments is a long term game
you cannot expect profit short term,because of many variables
but 1% house edge (or less at some casinos) ALWAYS factors in,the longer you keep your money
the more chances that you have steady,healthy profit
I suggest you invest at least for 12 months to be able to judge,anything less than 6 months could be even negative profit,because of the whales winning
and thus cutting the sites bankroll and everybody elses profit with it
