I mean, speculatively, you'd have to assume so (although maybe not right away). If you take away the supply, then you should see an increase in price. I assume not right away since most people are getting their use out of them already, so demand will also be low. But eventually the demand will rise again and the supply will shrink (until next anniversary) so yeah...
yep the price will probably increase 2x so save your scrolls and save them for after the event is over then sell
Yes. However they are going to continue to decline until the last week-two of the event. You’ll need to hold onto them for 6-8 months if you are looking to make the most profit. Something to consider is also that the event was released late this time, so if it’s on time next year there will be less of a gap and less profitability.
