It's good to see Bitcoin used as a unit of account, but I hope you will adjust the fees in case of Bitcoin value increase.
Absolutely! Fees will be adjusted accordingly if any major price changes take place.
The NETELLER card seems to be cheaper, but it looks like your card offers more flexibility (If I'm reading this correctly I could spend money directly from my Bit-X BTC wallet - on NETELLER I have to add funds as EUR, USD, etc. before making the purchase)
That's correct, you can spend money directly from your Bit-X BTC or any other currency wallet.
Can I set spending priorities for the card? (e.g. use my USD balance first then EUR, BTC last for card transactions)
Yes you are able to by setting priorities and limits for each different currency. This is still being developed and should be fully operational shortly.
The cards are not available in some countries (like the U.S.), but do they work in those countries when I'm travelling?
They sure do! Cards can be sent to these countries as long as the main holder is not be a resident of the excluded country.
Any other limitations we should know about?
All final limitations will be published next week (for the most part you can already read through them).
The jurisdiction of this MasterCard™ service is based in Lativa and everything is regulated by The European Union (EU) MasterCard™ rules.
What happens in case of fraud? Could you restore the BTC balance then?
This will be dealt with as per standard MasterCard™ terms of service rules. So yes, the BTC balance can and will be restored in the case of fraud.
Any more questions please do not hesitate to ask! Regards.
