Effect of removal of AH mount hasn’t been felt yet even tho ppl keep claiming it will drive the price down. The price has been pretty steady between 170k to 190k. Don’t expect this mount to have any noticeable effect on the price.
However, so far noone has been able to correctly determine the price of future tokens. All predictions made end-Legion, pre-BFA, in BFA and end-BFA has been quite wrong. For example, noone expected tokens to drop almost half price at the beginning of BFA, so if you wanna hold on to them do it but it is a risk.
