I'm looking at the virtual visa card, and it looks like its balance is denoted in bitcoins. Any information available on how/when they do the exchange? Costs in bitcoins for the service are here https://walletbit.com/pricing
. (10% of value plus 0.92 BTC, max value is 30.83 BTC)
At the time you transfer your bitcoins are converted to USDs.
So for a $10 Virtual VISA, the fee is 10% + 0.92 Bitcoin
So ... $10 + (10% of $10) + 0.92 BTC.
that's $10 + $1 + 0.92 BTC
or $11 + 0.92 BTC
or 1.69230769 BTC (At BTC/USD for Mt. Gox last, of $6.5 ) + 0.92 BTC
or 2.61230769 BTC
So the $10 Virtual Visa costs $16.98 USD. Of course, most of that is due to the 0.92 BTC fixed per-trx fee.
