You are really in your element when you talk about cryptocurrency and how it can change the world.

You make explaining things so easy and most people are aware that Bitcoin is an energy hog and this is one of the reasons why it is expensive as well as it valuable because of the increasing difficulty in obtaining it now.

Just like gold, diamonds and even oil because of it finite and difficulty in obtaining it that people are driven to get it and attach value to it.

I like the parts where you eplained POS and Dan's DPOSit is more cost effective and better in the long run but one of the fundamental problem we have there is being in the hands of whales to have a say on matters.

What is to stop banksters to buy the stake and choke off the system.

The POA though looks more viable.

Right now the blockchain technology is still in its growth stage. No longer an infant but more like its in its early childhood and will have a lot of things that will fail and experience.

With the experience it will gain,will just add more knowledge and build a better product.
