Total rubbish, PLEX price has been rising for years and at no time has it been “stable”. It’s easy to assume the price it was when you started playing is the stable original price but it isn’t. PLEX has always gotten more expensive and will continue to do so, people have always complained and theory-crafted and they too will continue to do so.
This is normality, these “EvE is Dying / PLEX is very Expensive” threads have been echoing in the void for many years in one form or another. Better to accept that PLEX is supposed to be a luxury and not a right, hence too expensive for many to afford and rightly so
