Ethereum as the most actively developed blockchain [...]
It’s not. Bitcoin is; but you obviously are not a developer. I follow Bitcoin Core development, and I am familiar with the codebases of some altcoins; I know first-hand whereof I speak.
I advise you to go for more learning and stop behaving as if you know it all, I know your type. I repeat, Ethereum is the most actively developed blockchain. I am not a coder like I had iterated, yet I research a lot and stand by everything I write on the Bitcointalk forum.
