How does pricing work? If prices in BTC, does it change everyday? Every hour?
Yes i think they will update the price every hour because the price of bitcoin is always fluctuating and that update will be very difficult for vending machines. It is better for them to use a stablecoin so that things are always stable like with cash. I don't really like the fact that bitcoin will be used to make payments at vending machines
What using for from vending machines where we know bitcoin and altcoin price is fluctuating where some time with higher and lower price, maybe although higher technology machine can't prediction about how bitcoin price later will higher or not because bitcoin keep stable without can't be prediction by any one else.
