So you are not willing to actually invest and have a mechanic business but you want to over simplify it for others?

It's the same energy as those who tell me I should have sold Bitcoin when it was 64K. I tell them to show me. They mumble and say Bitcoin isn't for them because it is too volatile.

If you or I understand Bitcoin then we can show others how to do it. I started a Bitcoin business in 2020 and I failed miserably. So what. I'm not going to tell another man how to run his business. A mechanic shop is not easy by any means. I know plenty of marine and auto mechanics who own their own businesses. Accepting Bitcoin only makes sense of they have enough FIAT to run operations and not have to sell Bitcoin to incur tax penalties.

A mechanic shop is a very visible business. They have state, Federal and local tax to pay in addition to vendors, power and utilities, point of sale. All on a Fiat standard.

I agree that is better money but I won't tell someone else how to run a business when I haven't done the same.

Make it happen. Go talk to mechanics and show them. Don't just make statements you can't back up. I wish you great success!
