Its not just patience that is problem, also is slow response from exchanges when big money is involved, I mean on this when some coin is gain price rise all want in then when you come to this price went double or triple. This is problem with all exchanges especially with big ones.
With masses of volume and everyday request, it's hard for exchanges to deal with their customer everyday. Plus include that some of the tickets needs further investigations which will take lots of checkings and verifications.
Because there is no law about that, we don't have a choice but to deal with that. If all exchanges will be strongly be centralized I think there will be changes since goverment will now have some actions for that slow response from the exchanges. But the downside, we don't want goverment to make a role here.
