Did you say you accept 3 coins? I'm curious what the third is (since you mentioned bitcoin and ethereum only).
The third is usdt because it is a stable coin and serve as a backing.
My plan is to hodl bitcoins as much as I can. Before now I usually keep 40% of my monthly earnings in bitcoin. I'm not worried about the volatility of bitcoin. I'm a strong believer in bitcoin and I'm in for the long term.
This is quite good for the adoption of cryptocurrency and seems like it'd be about as easy as contactless - just scanning a qr code, putting in the amount and going from there.
If you grow further, you can issue payment requests to customers either via a tablet or a screen on your PoS if they ever send the wrong amount as then you'll be able to set how much you request (with the qr code request mechanism, you can give them each an individual address to pay then too if you wanted to anonymise yourself).
Thanks for your insight. I think that's a good idea

Nice to meet a colleague here. My country men are fashionable and like to express their culture in their clothings. Thanks I will be creating an ANN thread soon. Hopefully I would get good response from the community.
