People might want to participate in and support the Bitcoin ecosystem, for economic, political, or technological reasons. People might just be curious about the technology and want to play with it.
That's a little abstract.. Without deep diving is there a quick summary of the economic/political/technological reasons why one would pay an extra 1% fee to pay this way? Apart from curiosity.
For me that's actually cheaper than what my bank charges for international transactions and transfers. I need this often enough that it would save me quite a bit of cash. Also there's no fee if you have existing bitcoins by the looks of things, so the 1% is just a convenience tax, afaik there are cheaper ways to buy bitcoins that circumnavigate this. I admit to not knowing much about bitcoin, but this product has piqued my interest as it might solve a few of my banking woes
