Staking is not the reason I hold ETH. It's the amazing projects that are taking place on the platform that keep me holding.
As long as it remains the Top platform for dApps its worth keeping longterm and once the dApps hit mass adoption it will skyrocket.
When a better and more popular platform will come along I might jump ship (I hold EOS too)....but frankly I don't see it happening....Ethereum is an ever evolving beast and has the developers in place to keep the technology always at the cutting edge.
