That is partly true. The Dutch 'Amazon is vol.com. They first started with Books On Line. Now they sell everything, publish and you can.use them for your 2nd hand books too. It all just depends on were you live and how hard your own country makes it to order, the taxes etc frequently are too high to make Amazon interesting.

It will be the same if it comes to the blockchain and cryptocurrencies. It all depends on where younlive itf it will be a success.
