Well the problem is: Which features should have the foundation of the future crypto development, allowing other applications to build on it? Can Ethereum fulfill these requirements since lots of cryptos are already based on Ethereum, but PoS is not even operative after years?

It is very difficult to list these features and their importance because they project into a future that does not yet exists.  Rholang, the new language to program Rchain and its contracts is very powerful, but at the same time secure, and easy which is a very difficult combination to achieve.   This will open a lot of doors.

There are two independent venture companies seeding many new applications on Rchain such as secure permanent identity impossible to forge. I see far lower risk now.

For me it is a way to help build a future I like.
