I'm assuming that the local exchanges you are saying is in the Philippines right? Because I read that they have plans to open 20+ for now and then 60 in the next coming years. That's a lot of local exchanges. Even locals coins.ph now have its own trading platform so everything looks good in the Philippines. In a wider perspective, it only means that there's recognition that bitcoin and crpyto will really exploded in the next 5 years or so because of the continuous growth of crypto money. People now finds crypto a safe haven for their money investment wise or even grow their money doing trading. However, competition will be tough in this area, because some well known exchanges have a good head start and those planning to enter the field will have their hands full on how to get some slice on that big pie, a multi-billion dollar industry.
I don't really see any point in creating that many cryptocurrency exchanges. Are we even going to reach so high volume that we will see thousands of exchanges? Some people prefer to use the most popular exchanges which are not based in their country because they trust them. And why do they trust them? We are discussing this problem here:
