The financial world is rife with abuse. If you look at the recent scandals from Libor rate manipulation to dark pool activities, they are on a massive scale and while banks may be handed hefty fines in multiple jurisdictions, the customers who lose out are often never compensated.
The misselling of PPI being an exception in the UK. In regard to exchanges I agree the ones who are seen to provide good service will survive, the others will inevitably fade over time. As regulation begins to reign in worst practices, certain exchanges may totally cease to exist. But what about wallets closed for maintenance which confer an advantage to the position of the exchange ?
as I said in the article, in my opinion the exchanges are getting away with actions which are totally illegal in any other regulated industry and while I don't want the fledging blockchain sector to be screwed into the floor by over regulation, there needs to be some clarity about what you can and can't do in relation to trading.
