[q] unboxed high tier knife. Help?

First time post and need some guidance,

Tonight I was feeling a certain way and decided to spend some money opening spectrum 2 cases, invested around $150 and ended up pulling a ST FN Butterfly knife Doppler Ruby.

I’ve done surface level research on the value but I honestly never really got in that deep on knowing float values or patterns, or any other nuances that can effect value.

I read the rules of the sub to make sure this type of question is allowed, so if it’s not that’s okay.
Should I unload this knife or hold on to it? What are the easiest/safest steps for me to taken if I decide to sell? I don’t want to get scammed or lose potential profit.
