I do confirm , you cannot sell your HXT in the internal exchange (your order will seat there with all the others and get canceled eventually all at once) and I also do confirm that if you had previous BTC earned before from interest, if you try to withdraw you will get a fake TXID and nothing else and your money is gone, atm this is a money trap, they used to pay but it was last year.
Did you withdraw BTC and that happened?
Yes, exactly...twice, so this my personal experience for a total of 0.02 BTC (0.01 each)
TXID: 0d12b453d10ccf7cdbd226419477a67619991575e6f496c3665a409be4542c67
TXID: 3878a866cc7bf1a7bca06cc5420fab613a96f7f530ad8c03151273075bcadddd
I contacted and report the issues twice, around 2 weeks ago to their special URL request.hextracoin.co but they fixed nothing, they used to pay well but that was last year before their HXT GOLD, unfortunately now they are not addressing those fake TXID BTC issues and my BTC have been deducted from the web platform balance so...they are gone.
