if you are going to use Ethereum platform how long will that take to make a transfer via your system? Just average. Have you tested it yet? Ethereum has a problem with scalability and your plans include well populated areas. How are you going to handle huge traffic?
this is a problem we are acutely aware of. We are moving forward at the moment with ethereum, but we are wallet & blockchain agnostic and will be eventually moving to another one that will allow us to scale and transact quicker.
Maybe one of these new DAG based crypto's I'm hearing about. Like RaiBlocks or Byteball?
