Yes it's true. I have no idea that theres a casino offer 0% edge at this time. The question here is ,if the casino has 0% edge, how do they earn? Offering 0% house can actually be profitable? Or they may make it for promos or attract new player to visit their website. Anyway,whatever it is I hope it is not scam.
Its not a scam, its a reasonable way to gain market share which is not often an easy task to do in any industry. If you observe something as mainstream as Amazon then they also run very close to zero profits seemingly at times, but also they have vastly achieved the task for gaining market share in not just USA but worldwide in quite a short period of time relatively.
Nobody could say this close to the bone strategy is a failure then, the risk is that company must keep growing in order to justify such an aggressive approach and be extremely efficient and well supported by capital when required. As no profits are building up they rely on the revenue of past expansion to allow them to continue, all growth must be valid and well chosen business or it would be two steps backwards.
Long term I dont suppose 0% edge is that feasible as the company must ensure security and other measures to operate, its not a factor which can be ignored so there is inherent costs to operation. Scales of economy do also justify gaining custom as fast as possible though.
