Yup, but that’s for the dApp-maker. So when you go to a forum that uses the EOS Network, you just visit the url like you did with this forum. But the one providing the forum is staking some EOS and gets resources for that.
So for a user at home the tokens are there for payment, ICOs, tips and probably a lot of other things, but you don’t need to stake as far as I know.
I guess they do, but don’t know the exact number. More important for them is to get votes from the dApps that are staking tokens.
