It is interesting how you monitor this.
Well, I have hivedex.io open at all times, but I only get to that tab every once in a while. And if HIVE pumps unexpectedly (usually when the general market is sideways or slightly in the red) and I notice it, I do check the volume on Upbit, because there is a history of pumping the price via that exchange even from the time of the legacy chain.
Yes, I know of such history. So do Koreans buy using KRW? And can we see that on Upbit?
Well, the HIVE/KRW pair is the most active for HIVE from the ones tracked by CMC. We don't need to see that on Upbit. Of course, there can be wash trading, to increase the volume, but they certainly have a lot of HIVE on Upbit, so could be real trading.
I have heard of such pumps 3 to 5x in my over two years on Hive. Time will come I can take advantage of it.
