I have invested .23btc in it in the first phase of ICO, I was able to sell 90 Hex and take .23btc that I was successfully able to transfer to my Bittrex wallet (Made my initial investment back plus extra $472 cuz btc went up). Currently my 1000 Hex coins are sitting on the exchange and I would believe they are doing manual transactions or something at that time and I saw somewhere only 1100 transactions for BTC went through, which means they definitely needed this upgrade/fix. I would hope they come back and we can make bigger profits eventually.
