What about something with Amazon
Basically, people could buy anything from Amazon but within your site. Not sure how to implement the idea. Maybe using services like BitPay.
You could make a clone from Amazon website, people buy items (delivered by Amazon) and pay in cryptos. The coins are converted to fiat automatically (with Bitpay or any other) and your Amazon account is automatically topped up with a bank account (the one you used to receive BitPay payments)
I thought to do exactly this.
And as far as I remember amazon actually have a white label service and an API.
But upon further research I seen newegg and others already accept bitcoin directly.
I am good at making sites but not good at marketing I don't want to enter a market that is saturated.
I want to produce something unique that is useful and to be the best.
