OP, are you trying to steal Business ideas from over people and make them your own business? Nice try. 
If I ever had a working business idea, I would never share it with random strangers on the web. Knowledge is power. Don't give it away for free.
Good luck trying to open an online shop and accepting Bitcoin payments. I'm sure that you will get thousands of customers every day.
I have an idea about a crypto casino, that is going to be different than all the other crypto casinos, but I'm not going to share it.
It's not specifically about BTC, so I guess that it doesn't fit in the "Bitcoin business idea" category.
