I think the ETH staking rate is very low.
You may forget they recently switched to POS, so staking level slowly grew over time. And there is another "issue" with staking on Ethereum. There is a 32 ETH minimum staking requirement, which pretty much makes staking a whale game or done via staking pools. But there may be ETH holders who don't want to give control of their ETH to a pool, in return for the staking rewards.
Even in Hive, this rate should be around 40-45%.
On something like Hive, you can stake even 0.001 HIVE, so no lower limit (or upper one, for that matter). If we disregard the liquid HIVE on Upbit which seem to never move out from that exchange, the staking ratio is much higher, which yes, I believe can be an issue at some point. Despite all that, HIVE seems to be one of the most active coins on the markets when it comes to daily volume, which is an interesting aspect to remark.
