- Exchanges typically take a percentage-based fee for every trade. The exchanges that don't take a % fee on a trade take a % fee on withdrawal. The one's that don't charge a fee, front-run/sell their own users to high-frequency traders (they call this "order flow") who then make their own trade based on any significant trends or actions. Taking a % fee is not in accordance to the spirit of Bitcoin, at least in the sense that if you transfer Bitcoin on the blockchain, it's for a fixed fee that is for the most part independent of the amount. So I believe an exchange that charged a fixed, fair and predictable fee in addition to not selling their users or their trades could be s disruptor.
Am I totally off base? Always curious to know what the Bitcointalk community has to say. So if you have an opinion, please share it.
I dont think there is need for any disruption because every option you listed up there have one thing in common which is profit motive. It now depends on how aggressive the proprietors of such platforms and other market factors that determine which of the options available will be implemented on such platforms. In your own case, I think you need to consider the option that would give you the needed cashflow that would keep the business running till it gets it footing before you can consider other options in other to expand.
