Oh boy I actually invested money into a strange machina and it's value increased by 20% since mmm~
invest in EVERYTHING IMPOSSIBLE TO OBTAIN NEW VERSIONS OF THAT PEOPLE WILL BUY
i bought strange holy mackerel for 6 keys, it's 12.5 keys now
i bought strange festive minigun for 8 keys, it's 25 keys or something now
i bought regular festive minigun for 1 ref, it's a few keys now
this applies to tons of items
