Re: Any services like TheBigCoin? (Pay fiat invoices with Bitcoin)
I think this could be a pretty popular thing if implemented correctly. I would probably use such a site instead of buying giftcards for amazon @ a 10% markup rate.
I considered the demand too low for such services (maybe wrongly) and the fact there are already a few websites (as quoted) old and established for some.
Basically, I could even process to pay the bills instantly for the EU and use other currencies for others. As well, a gift cards option, (with a 1:1 rate and no crazy rates). Can't say much, in case I was wrong (I'll do a KW research again) but it was something a little more advanced
Perhaps people feel more secure with giftcards since they can attach them to their own account...?
If you don't need a lot of liquidity to create something like this, and you can wrap it in a good UI, with clear instructions and detailed information (extended dashboard with shipping information etc.) I think it very well might be worth trying.
Although, i don't really know whether amazon et al will approve of this, since basically you'll be, (if successful) ordering 100s if not thousands of products from the same account(=same IBAN/BIC rather) shipping to different adresses.
I can already see a lot of problems arising whenever you try to scale it..
Looking at something like dashbargain, -- it might very well work, but it doesn't seem to be A. automated, or B, very userfriendly. They basically say "submit your order and we'll see about it and send you a coinpayments link later." with little to no other information. I feel like a lot of people that don't know about them aren't inclined to use them.
I don't know, perhaps i'm overestimating the amount of people that actually use Bitcoin for shopping as well, considering other websites removed their BTC payment options after implementing them.
