Best coins are those with real life rules - stable amount with tiny inflation through block emission, coins you have to earn/buy.
On downfall will always be coins that ignore these rules.
Coins you somehow "get", by staking or airdrop are always ending in crazy inflation spiral.
Or like XRP, which as corporate works on controlled pump/dump media PR+coin emission.
Not true, there are many examples of coins with POS that don't suffer from this conundrum.
Name one.
PIVX.
PIVX is best example and still worthless (apart from couple of gamblers buying, offer/demand ratio is 10:1 or more):

Ooooh worthless is a pretty strong word. Plenty of use cases. With correct personnel it could have been adopted much quicker.
I personally use it almost daily, and of course the offer demand ratio is off, it’s a freaking bear, what do you expect.
If the demand/offer is 1:10, then it's worthless.
In last 90 days, it on constant decline. Best way to secure your assets is to take all reasonable "buy orders", because each day it would be worse.
I really think you're knowledgeable fella, with decent experience. So you can afford little bit of loss on PIVX. But don't lose all waiting for miracle to happen.
