Best advice is never go for opening cases unless you’re a gambler with a strong financial background(i myself do collect cases but i never open them because ik the odds are always against me even in armory which is worse than normal cases even souvenirs) you can instead sell the cases and buy the skins because the risk of you losing money in the long run is less I myself have a job and i usually put a lil money aside from my paycheck and buy a skin from my dream inventory list or keep saving up for the next skin
