I read your post and feel dumb after doing so as usual. You can have a personal collection and treat the hobby as an investment also. The two aren't mutually exclusive. No one cares you have to sell to open up space. No one should care if I sell for money. Get off your high horse you sound silly.
Hey man, is a personal opinion, if you don't care then why address me?...like I said was into kicks, been into toys, I've resold when I've needed extra cash and taken advantage of the market value at the time I needed the money, but collecting for monetary profit is dumb, if you want to invest, there are far better investments than collections....saying "you are getting out the game" discredits you as a collector and just makes you a hypebeast, putting down one collecting trend, ready to hop on the next....collect for the love of it....
