I'm interested in starting a hot food cart serving plates for USD but half off for BTC. What's the best platform to use to accept actual BTC from customers? I imagine some may be willing to spend some time setting up an account to buy food effectively half off and this can help the Bitcoin community by expanding the userbase.
Of course I could just use proceeds to buy BTC (which I will) but I'd like more people to use Bitcoin in general. Any input is welcome.
