not on Polo, so hard to get a major price surge.
Bittrex has a lot of volume nowadays. Being on Polo helps a lot, but being on Bittrex can achieve wonders by itself. Korean exchanges can make a big difference on top of that though.
I think in the long run decentralized exchanges will overtake centralized exchanges. How many people are complaining about kraken and even bittrex withdrawel limits and KYC programmes. It will only take one or two big new hacks to make most big players want to go to an decentralized exchange. From next week, waves platform with its dex and NG will be miles and miles ahead from any competitors. So maybe right now volume on any exchange is relevant to waves price, but I think we will be seeing a huge influx of new traders on (waves) dex. Also, with every new gateway will come new traders.
To add to this, if there are 100x more transactions than at this point, leasing 1000 waves will give u about 1 wave passive income weekly (not factoring in the new leasing rewards). I think this will happen in not too distant future.
