It needs bigger exchanges, and exchanges in many countries such as korea and japan
I don't think it need bigger exchanges while Waves already have functional exchange in wallet from my point of view we need more people to adopt this network for trading and more volume to make it more valuable coin.
I think different about the exchange subject.
Every reliable exhange brings liquidity to Waves. Yes, DEX is getting bigger and better, but that doesn't mean more liquidity isn't needed. Even if Waves DEX is the biggest one.
And let's say an altcoin is just listed on Polo. Does that mean Kraken, Bittrex or others, or local exchanges are not important? I don't think so.
But it's all about the priorities
As I understand team's focused on some other things. And I agree with them.
