I also withdrew bitcoin and it remains pending. As the exchange is in beta, for security reasons they have kept minimal btc in the hot wallet. as they are low they will have to top them up so we can withdraw. I am assuming the devs have taken a couple days off due to new years holiday, but when they are back i am sure they will sort out the withdraws, in the meantime we just have to wait. There is a bright future with VLX, cant wait to see what happens when people realise this undiscovered gem!
