Some may think that it is bad for us but I don't think so, actually it is good when we can choose whatever we like when it comes to exchanges and trading, wide choice is not that bad.
Its stupid to say that many exchange=bad situation.
Cryptocurrency mean decentralisation
Decentralisation mean many exchanges if some will force you to KYC or prohibit some coins you will always can say to them "okey I go to another exchange"
