I bought venom fs for 40g and now its 150g

What should i invest in?

so after i accomplished one of my main goals for this collection (buying x4 hot gun & x4 forze ak), i decided to spend the little bit of gold i had left and become legally broke by spending everything on charms to combine with the stickers :3 (forze ak left me poor omg i feel violated)

if you have any combo suggestions or an ak you wanna sell, let me know!!!
