I messed up big time

New Tarkov player here, just unlocked the flea market and had a few millions saved. Sold a bunch of my lab cards and notice there were unlimited colored ones. Here I tought "Unlimited? Damn that's a nice deal for 4.2 Million, i can just run labs forever and get good" So I bought a violet one.

Well guys, I don't have any money left and turns out it's not a card you use to get inside. Kill me
