You should post a proof of you brought this gold or it considered as worth less because if you have accumulated this gold from referrals then surely soon or later you will loose this gold when you try to withdraw it. Good luck with your selling.
That is true. Do not risk your money by buying referral gold.
Some one has posted his account proof here. Look at it how all those accounts has been suspended. There must be going on something fishy with bitgold.
