Staking in ETH is have difference than Staking in some project, the staking not only benefit the stakers but also the network since the staking process is securing and powerize the network.
So, theoritically with so many ETH locked by Staking process will lowering the supply of the coin in the market, securing the network, and probably make the price rising stablely.
ETH 2.0 means to be upgrade for Ethereum, it will bring a lot of improvements to the network. If they are successfully running it that means the upgrade does bring something good for the project, then why not follow it and do the same thing too since it is also good for their own.
what is the con for doing something like this? not being the original? I do not know.
THANKS have done with 16 ETH... not a lot but will see , but better than nothing . enjoy guys carpediem
