[Question] How much is the new crate going to mess with the RL economy?

Probably a stupid question but I'm still relatively new to RL trading.

I've unboxed my second Hexed and I debating between selling it and keeping it. A friend of mine is constantly telling me to sell it because it's value is going to drop. His plan is for me to sell it and then re-buy it when the price goes down. But how safe is this?

I mainly just want a Biohazard, but this falls into selling the Hexed and then waiting for prices to fall. If anyone has any insight on a smart move for this that would be fantastic, thanks!
