Good Day fellow Bitcoiners

.
I am an entrepreneur and also a Bitcoiner, I have two
business which am running and in this two business
I accept Bitcoin as a means of payment .
When ever a customer desires to pay in Bitcoin/crypto in my absence, I am usually contacted by my employees. I have explained some few details on how to receive payment from customers in crypto but I think they still find that means of payment as not being convincing, so I want to take out time to teach them Bitcoin, advantage, users, how to receive and how to send Bitcoin. I want to give them a full knowledge about Bitcoin. My request from this forum is to give me more hints on other things I must lecture them on concerning 😟 Bitcoin and how to receive payment from customers.
Thanks, Detritus.
