I think US$850 is for the security check, not the whole wallet. Please get your fact straight

You can't buy the wallet as sadochismo put so much times into this without charging.
Next time, do some own research will you?
"3. Hondo and I just bought 36016 XST from the premine at the last trade price 0.00002721, which equaled $330 USD, to fund completion of the wallet, as part of an $850 payment. This will go out of the premine as two transactions of 18008 XST each. The XST payments will be sent soon."
Where do you see security check being mentioned anywhere?
If it's poor wording, it's not my fault.
