There are over 500 crypto currency exchanges in existence with new ones created by the day. Should there be a limit to the number of crypto currency exchanges in the crypto marketplace?
It’s the open market doing its thing.
The more competition = the better conditions for the traders.
Competition is what pushes the market/businesses to constatly improve. If they don’t - their service/product will not be up to par and will be pushed out of the market by their own clients (by them choosing a competitor’s offering).
IMHO, there should be some limitation/regulation, just to ensure that the exchange is a working business and not a scam.
Other than that - as a customer/consumer of such services - the bigger competition in the niche is welcome.
