I have tried to display a reminder of accepting cryptocurrency payments in my shop.
But many customers don't know what cryptocurrency is. Some interested will ask, I also have to teach him how to buy it on the exchange and then how to transfer it to me. This wastes a lot of time.
In a month, no stranger pays with cryptocurrency except for a friend who understands Bitcoin. He used Biance's C2C function to transfer me a 200USDT bill. Finally, I removed the cryptocurrency payment method.
It takes a long time to promote cryptocurrency payments.
I totally get the frustration. But why not leave it in? It's not like the sign was harming your business or something. Yes, you're not getting the results you wanted specifically(receive cryptocurrencies), but think of it this way: because of your sign, other people get interested in this space. Which is still a win in the end!
Unfortunately, under the influence of the epidemic, my shop closed down. If I open another store in the future, I will continue to show it, and a single spark can start a prairie fire. As you said, victory will ultimately belong to us.
