Assuming a merchant accept Bitcoin,
You as a shopper, place an order, and that merchant did not deliver, or sent to the wrong address, or sent a fake product.
You can not reverse the payment, you can get your bitcoins back, and the only thing you can do it leave a negative feedback.
Of course, there are many other scenarios, like phishing websites, fake websites, selective scams, and so on
What are your thoughts and ideas to prevent these scams.
We cannot get our bitcoins back modify the op. My idea to prevent to this type of scenario is just always use escrow when transacting to merchants. This is the only way to prevent merchants to do this crazy act. And when it comes to phishing and fake websites, just always be cautious and learn to look at the url to protect yourself.
Yes but using escrow for every purchase is a recipe for the failure of bitcoin. I'm a big online shopper. If I had to use escrow every time I used my credit card to buy something online I would cut them in half and throw them away. Credit cards would be useless for me then.
I'd much rather take my chances on losing my btc than use escrow for every purchase. I just don't buy costly items using Bitcoin. I use credit cards with fraud protection for those items.
