Staking is very similar to what we can find in the traditional financial markets...
Yes, including long-term downtrends for most fiat currencies (vs. gold-or food-for example) and (for POS coins) clear downtrends vs. BTC in many cases. This "very similar to what we can find in the traditional financial markets" is somehow a good thing?

Don't you worry that PoS will overtake PoW?
No, cannot remember the last time that happened.
