hello ETH believer's , i came to bring a good news for you.
for now, of course ETH still on PoW right now. and PoS system is not released yet.
and if u asking when PoS begin ?
according many many and many articles i read , Phase zero of ethereum 2.0, which enables Proof of Stake (PoS), is targeted to launch on the 3rd of January 2020.
sourceIndeed this is good news for some people who invest in ETH, ETH prices right now are not good, and everyone is waiting for surprises from ETH like 2017, and I believe the ETH team that has very good performance will provide the best service for ETH, so not a few ETH is one of the currencies that investors aim for.
