50% is if there is no transactions (ie> losses of fees and coinstakeage), everyone stakes optimally, and other factors, it's really not possible to approach 50%. What the actual % eventually is remains to be seen.
It's much higher on some other coins 100% or even much more. so far it hasn't really been an issue as you can see in current supply after 6+months. There is the potential of heavy transactions taking place sometime in the future resulting in large fee destruction. You can actually see this happen now on occasion with a large transfer, the money supply actually goes down (if fees > reward).
As far raising/lowering limits, this can be adjusted with a vote of miners/stakeholders to increase or decrease limits/ or other parameters (sometime in future if need arises). I feel if PHS ever needs a 'fork'' ie adjustment .. it can be decided by super-majority.
Thanks for the info. Whch coins offer 100%+ in PoS minting?
It seems too easy to just invest a lot of money in the coin and sit back and collect new minted coins. If the market value goes down and stays down then I'm in trouble but it not then I benefit from the minted coins. In this respect it's similar to some high risk bond or ETF that pays a high percentage but the unit price can fluctuate a lot.
Yep, I also forgot to mention that exchanges (and others) usually don't have stake running for obvious reasons, so that's another ~10-20%(perhaps more) of money supply not creating inflation. This is actually likely the biggest offset to the '50%'
Also, if you buy PoS vrs PoW cryptos, you can always just put them in wallet and create stakes if market goes the wrong way for you, and wait it out or just have a steady income every 5-10 days(PHS) to sell off (or compound). And yes its very similar and i suspect many use the stake return for a steady income. You might want to start small to see how it works in real-time (or use testnet which is hundreds of times faster) .
I have some PHS in wallet since Jan 7th, but still can't get the pos reward, why?
wallet encrypted?
