If you _really_ trust them, you can buy a bunch of BTC on any other site, transfer it to wex and buy tokens for it, effectively doubling your BTC. But it does feel like quite the gamble though.
This is crypto. I'd much rather take a gamble on various altcoins with decent charts and fundamentals, for a shot at a 10x-20x whale trade. Given everything that's happened, half-price doesn't seem like nearly good enough of a deal. Even if you assume that they will remain operational for the foreseeable future, even the site admins themselves (on the forums after the takedown) said that the tokens would likely take 1-2 years to redeem. That's a lifetime in crypto.
