I mean, it depends on what Tom means by insane currency. I think he has a point. I've played 3 characters in this league, levels 87, 91, 89. I haven't sold a single thing, and purchased quite a few things like a 6L Infernal Mantle, Kaoms, Astramentis, and a few other pieces of equipment worth a few Exalts. I still have 8 Ex on my stash, a couple hundred chaos, and a bunch of other currency I could sell.
Still don't think I could afford some of the builds out there, which is what I think Tom is saying. Even if I sold everything right now I'd probably have 25-30 Ex, which is barely what Atziri's gloves cost, and I wouldn't consider that an insane amount of currency either, in fact I would consider myself quite "poor" compared to most. Some people spend that during breakfast just trying to get 1 more stat on a ring or something.
I think being at the top bracket, knowing what to run, what to sell, what services to offer and charge for, etc. is a very hard thing to do, and something that requires great knowledge of the game and dedication. Some builds are definitely way out of reach for players like me.
