It's possible that in the future every country will have their own exchange, exchange is a huge business and every company wants a slice of the market, for me it's not tright that 10 excahanges will control the whole market, the more exchanges the more volume and they are going to satisfy investors to meet their standard.
Everyone will not like all the 10 exchanges because they have their own issues with the exchanges and that's why we need more exchanges. Based on the demand we might see different exchanges will launch in different countries because every coin will not pay higher fees for listing the coin in higher volume exchanges.
