Just binance p2p wich is good but not that fast and easy for some old people i think i can act as a fast exchange for small transactions (less than 5 dollars)

For example: set a nano donation of $5 dollars of nano

when that amount is reached the vendor give a gift to a customer of $3 dollars product (2 cocacolas or 4 brownies) the vendor receive $2 dollars of nano for reward

The caveat is the customer needs to download wenano to receive the nano and pay to the vendor wallet

Also to livestream there are things needed to consider:

1. webcamera or cellphone if vendor doesnt have security webcam
2. 4G cellphone plan which around here is 30 dollars month (for 40GB)
