Highly recommend checking out the STEALTH technology that is being integrated into Bitshares. Three second transactions at up to 180,000 transactions per second... absolutely private, untraceable, blinded. Think about 100% private economies that can scale to 100x what Visa or Mastercard currently do (globally) where guys like Luke could be funded and banked with absolute privacy from censorship and seizure. Imagine how many more people would support alt media if they knew they could do so without fear of reprisal, how many more journalists would create content if they could get paid in absolute privacy and how many more alt media outlets would flourish if they could generate revenue and pay bills/salaries without having to go through fiat banks. Bitshares is making it happen right now...
