i don't think that we can help them, they have to decide on their own
We can help them, we just need to explain to them on how bitcoin can be good to their business and how it can boost their sales. Especially if their business is an online business, their transactions can be on instant and while bitcoins is in their wallet. The chance of getting higher profit as the price increase is happening, it can give them another opportunity.
Interestingly I have convinced my local shopkeeper to start accepting bitcoin payments, but unfortunately he is not finding many bitcoin payments and no significant improvements in sales.
This may be due to lack of bitcoin adoption in my area and also even some people are adopting bitcoin still they are not ready to spend bitcoins right now.
That's good to know if you had convinced your local shopkeeper, don't worry it is a step by step process. So the next thing that you need to do is advertise and let those customers know that the shop that you are sharing knowledge about bitcoin is already accepting it. It may took a little time before those customers will have total adoption in bitcoin but what is important that you already advertise bitcoin to them.
