There are hundreds of exchanges and more to come. No wonder, cause it's a great way to earn money for developers. I agree, that the number of exchanges shouldn't be decreased. This is a sphere where competition is extremely needed. But strict regulations are also should be launched. Anyway, I'm not sure that we'll see any changes here soon. So make sure you trust your money to reliable exchanges.
Exchanges are evolving too. There are new exchanges that offer transaction fee mining. The innovation keeps on going even in the exchanges space!
Its just one of the signs that crypto market is growing, even thou prices are declining. Innovations are everywhere around in crytoworld, we here see it, but people outside see only the price, nothing is more important than price, its sad, but thats the world out there. Thats why I`m not worrying about this drop, its simply bad time for crypto, but we will recover. Technology will win in the long run, we passed trough much worst times I believe, we will survive this too.
