The chart above Is only for the day. I observed the same last day as well. It happens just before the market close candles. 5AM (GMT+5) here. I observed the same thing yesterday and today when woke up. I didn't tried to look into the matter but I had thought someone is just trying to get higher market closes at the end of day for hive in order it to push higher later or something like that.

It may be koreans, as Upbit is having around 10x more volume than Binance usdt pair. Whoever it is, we will see. & I don't think SUN is up for another fight to overtake HIVE as we can always fork and transfer the network. It can just make us a bit slow but we are going & building.
