The steam market for this continues to interest me.
Earlier today the prices reset for the crates and the survivor/wanderer went through the same typical price cycle of a big drop in price once the extra supply rushes in. More interesting was that the gamescom crate was very briefly still available in the game after the price reset. Many people bought them up for 700/1400/etc. BP and dumped them on the market, dropping the price to $2.20. Then shortly after the crate became completely unavailable and it went back up to $3.06, where it is at the time of writing.
If steam wallet funds were withdrawable to paypal someone with capital could make alot of money out of this, even with the 13% transaction fee (which is so high!). Although I suspect if that were true, then alot of people would be trying to do just that and the market would be less volatile and less exploitable.
