Most people are skeptical without a good reason. In my case, I listed actual issues with the technology behind Bitcoin. Any store can implement a discount for any other cryptocurrency...
On top of all this, the curve that Bitcoin uses for ECC isn't very secure. You can look at the curves here:

Bitcoin uses secp256k1, with an equation of y^2 = x^3+0x+7, which becomes y^2 = x^3 + 7 for it's curve. The curve fails 4 of the safecurves tests, and was an unusual curve to begin with. There really wasn't a great reason for it to be used in Bitcoin, since nobody else used it, so it didn't get much review. Other cryptocurrencies don't all use this curve, lots of them use better ones.
