Hello!

Why is BTC-Withdraw unavailable?

It has a bad taste, that it is unavailable right now when the btc-rate is rising.

Do you want to make money with the money from your customers?

I hope for you that the BTC Withdraw come back very soon, before the rising is over and BTC-Rate fall down.
Otherwise it was pure scam what you did and you can be sure, trust in you will be lost completly.
