It would be a shocker if Satoshi started working on the next Bitcoin, because he saw that his invention was open for exploitation. He realized that
the flaw in his invention was the fact that it can be duplicated by anyone, if he could not reveal his identity and then protect his intellectual
property rights. So Bitcoin (BTC) was just the test run for the next Bitcoin, where he would reveal his true identity. I think Satoshi Nakamoto
is more than one person and this group are working on the "legal" version of Bitcoin.
I consider this idea though which might be possible but its hard to believe that he would go for another creation yet Bitcoin is already an exceptional innovative thing that had been created.Its hard to believe that he would consider on creating version 2.0 of it.Yes, there might be flaws but come to think that the main purpose on why btc is created is for total p2p and it doesnt need to be legalized nor be controlled and with that alone is already a solid reason for people to believe much on bitcoins potential.the flaw in his invention was the fact that it can be duplicated by anyone, if he could not reveal his identity and then protect his intellectual
property rights. So Bitcoin (BTC) was just the test run for the next Bitcoin, where he would reveal his true identity. I think Satoshi Nakamoto

I also doubt the creation of Bitcoin 2.0. To do this, there is a huge amount of altcoins to develop the functionality of crypto, in turn, Bitcoin is the standard of P2P with maximum decentralization and security.
