...but the caveat is that Amex takes the money from the consumer for the purchase, and then they deduct 2.89% of that amount for themselves as a service fee and then they forward Breitling the rest of the money a week later. I repeat. Breitling never receives the full amount of the watch purchase. They receive the total amount minus 2.89% a week later.
So with that in mind, of course Breitling would want to accept BTC through Bitpay. Instead of paying a 2.89% transaction fee, Breitling pays a 1% transaction fee, and instead of waiting for 5 days to get their money, they get it in 2 days. It's a friggin' no-brainer...
But what happens if the "value" of BTC drops 15% during that 2 day period, which has happened to BTC in the past?
We know it can go the other way. BTC could shoot up 15% as well.
It seems to unstable and volatile for the retailer to know what their income will be on each transaction.
