Thanks for the video post. You are correct that Steem has advantages over bitcoin. And I think one of the main reason people do not want to invest in Bitcoin as it stands today is because of those problems mentioned in your blog.
But if Bitcoin goes adopts the lightning network payment protocol it will solve a lot of its problems.
- Instant Payments: speed will be in milliseconds to seconds.
- Scalability: billions of transactions per second
- Low Cost: the Lightning Network will allow very low fees, which allows for micropayments
I agree with you completely. That will change everything for BTC and it's transactions will increase with the speed.
