But this idea that all Bitcoin 2.0 projects are fraudulent
Please, stop. There's no such thing as a Bitcoin 2.0 project.
Bitcoin is at version 0.10, and any project that works on top of Bitcoin but is not Bitcoin, should not be called Bitcoin.
I will agree with the above statement.
Bitcoin did NOT reach version 1.0 yet and it's still in beta.
How are some people creating "Bitcoin 2.0" projects really makes me wonder....
