I heard Ethereum will be updated to Ethereum 2 in early 2020.
I would appreciate you if you answer my questions.
1. Will there be a fork like we had for bitcoin cash? Or we will have to deposit our Ethereums to an address to get ETH2 in a new address? Or our Ethereum will be updated automatically?
2. What do you think about regulations? Is it possible that we will be forced to pass KYC to get ETH2?
Yes, there is a planned upgrade in 2020. Of course, there will be a hardfork. But you are asking the wrong question. A hardfork can be smooth with all participants jumping on the new network configuration. While a contentious hardfork may create a separate network like in the case of ETH classic.
KYC is usually enforceable in fiat gateways or centralized services, not decentralized networks.
