@hatu, it is good to see that people are realizing the true meaning of block chain. Despite a few hicups, we are recognizing that today's artificially inflated crypto currency is tomorrows fully centralised one world, digital currency, blockchain systems, and many more. Besides the obvious...one single crypto currency transaction consumes as much energy as doing 200 loads of laundry. Now scale that up as a global system of commerce....The globe can barely reach energy requirements as it is....where is the extra energy going to come from? Thanks to blockchain, we can now have tools like *IZIChain,* hoping for the best.
