How‘s it going after Mainnet ?

Hello, my plan was actually not to sell my Pi's directly as soon as it was on the mainnet, but to wait another 4-5 years and see if it might go even higher like Bitcoin or something like that (I'm sure it's never that high). I've already locked 50% of my Pi for 5 years in order to mine faster (or similar).

But now a friend who has been dealing with this sort of thing for a long time said that I should sell everything straight away, since all the pioneers have been waiting for years to be able to sell their Pi's and as soon as they do, the value will drop sharply because the value depends on how many people have Pi's. Is there a way to unblock the locked pl's or did I mess up?
