When you buy something on eBay or Amazon, you pay the seller, he ships the product and upload a tracking number.
If you haven't received the item, you can call eBay or Amazon and, basically, what happens is that if they have a tracking number that shows that the item has been delivered, then it is ok, otherwise eBay or Amazon reverses the transaction and you get your money back.
Is that possible with bitcoin? What if I buy a boat online for 2 bitcoins and I never receive it? Is bitcoin able to solve this problem?
Thanks
Yes it is possible, there is already an implemented payment method where users can buy stuff's at amazon using bitcoins and the price will be much cheaper since the value of bitcoins today is increasing. This means that the community of bitcoins is growing and might be fully use to different online stores in the future.
