staking is a term used by all pos coins. not just these two. who are you trying to fool ?
you are so desperate to draw links that what you says means nothing.
How many other coins have online "staking" wallets?
Hashstakers/stakers have nothing to do with POS, the payouts don't even match POS rewards. It's just a term deposit with interest. Calling it a "staker" and pretending it's an actual thing certainly evokes parallels, whether you like it or not.
There are coins trying to create real trustless pooled staking. Hint - it ain't ION.
