You cannot find one since there are no exact dates when the move from POW to POS will take place. Roadmap says staking is projected this year but I suggest not to hang on to that since it's been delayed so many times already. "Ethereum 2.0" has been scrapped and rebranded as "Consensus Layer" while the current Eth 1 will be called "Execution Layer".
I lost some possible money all because Ethereum failed to deliver what they promised seems to me that Vitalik Buterin has already lost that genius and Midas touch within him and his people are still lost on solving the main problem in the Ethereum network. And this is good news to other blockchain network which are mostly offering negligible transaction fees unlike the unbelievably high offered by Ethereum. Anyway, I am still hoping that Ethereum can get past of this obstacle to its growth potential.
