It's funny that I don't even recognize some of those names on there but that's because of the Korean element to it, no idea who those dudes are.
It's fun to see the account claim tokens stacking up, I'm getting up there myself, nearing 600 myself! I don't know what would be done with them but I do it as a way to use up my resource credits more than anything lol. I've created a few accounts with them but I just let them hang out. It would be cool to sell them back to the network or something at some point in the future somehow.
These markets are definitely for the nose to the grind stone building!
With the exception of Haejin, they are Chinese.
