Charles Hoskinson asserted on Twitter that the project to which he has dedicated more effort and passion during his whole life is Cardano
I bet if he says this is because he is indeed the founder of Cardano.
So, all his life is at stake to continue to support Cardano and develop it.
If we are referring to Vitalik Buterin then it is certain that Vitalik's intelligence is also for Ethereum, and if we talk about Cardano then behind him is Charles Hoskinson . Simple that !
