I read this post paragraph by paragraph, the english you use is easy to understand and it is readable, let me share some points that Interest me.

Blockchain is changing life every day which steemit is a typical example of it, helping people to say their mind and rewarding people for their voice

When it comes to storing of data, it is th best because all information can be traced no matter how many years that have passed

You also mentioned that blockchain consume a lot of energy.
Another point is that because it is decentralized many have use it to steal hard earn money from people since they cannot be caught, that is to say everything that has advantage also have disadvantage.

In all i will say I have to keep this post safe where i will always get it and learn more.

Thank you so much for your time and effort @focusnow
