Is DDR4 ram prices ever going to go up?

A few years ago, I bought like 8 sticks of 32gb DDR4 ram because I was working a job that gave me a tech allowance and I didnt know what to spend it on so I just maxed out my ram on my 2 systems. I see DDR5 ram prices skyrocketing but DDR4 seems to be pretty normal. Anyone know if the prices will go up eventually? I can't even price check the ram I bought because no one is selling them.

This is the ram I bought like 3 years ago. Is it just too old and not worth selling?
