What to stock up on?

May I ask how much Pieces of Time are selling for? I have been buying a lot of them in Kradia for ~2.5m, as I expect them to be more than this for sure. Any rough estimates on their price afterward, by basing it off of other versions?

I must stress time and again that we cannot base our predictions on prices of other servers. What we CAN do, however, is look at % based inflation. Say, if they went from 1m to 5, they increased 500%. Therefore, where ours are currently 500k tops, we could expect them to hit 2.5m (note this is just for explaining my point, not a real prediction).
