It was possible to get as much as 85% by waiting until they refunded 68% a couple weeks later and selling the tokens they gave. Some people even double down and invested in tokens as wex was paying their debts until it shut down.
Well.. I made the mistake at this point. Although I quickly withdraw my BTC, I kept LTC and other alts in Wex.nz, along with the tokens. And rather than immediately selling the tokens, I waited for their prices to increase. And when Wex.nz was closed down by the authorities, I lost all that money. I guess I lost around $1,000 worth of tokens and coins back then. The current exchange price would be somewhere around $50,000 to $100,000.
