Anyway...
scenario A Eth PoW using efficient asic:
Eth PoW hashrate ~850,000Ghash
eth asic of 2.4ghash at 1.92kwh per asic
=354167 asics = 680000kwh = $27,200/hour
there are ~260 coins made an hour = $104.62 electric cost per coin
scenario B Eth PoS solo stake:
Eth PoS solo validator ~420,000
Pc solo validators of 100w per pc
= 42,000kwh = $1680/hour
there are ~260 coins made an hour = $6.46 electric cost per coin
scenario C Eth PoS custodial stake:
Eth PoS solo validator ~30 custodians
= 3kwh = $0.12/hour
there are ~260 coins made an hour = $0.0046 electric cost per coin
thus, the underlying cost of security/creating a coin drops with PoS and drops further the more popular a PoS becomes. (both cost and security)
where by the difference between the underlying value. vs the market price is made up of pure speculation of human choice. rather than an underlying cost
I wonder if ETH will still retain its store-of-value properties after the POS upgrade, in the long term - as in several years or decades from now once governments become smart and realize that they can just issue a warrant to POS miners they don't like and seize their equipments in typical raids.
store of value "properties"?
store of value is just that. a store of value
value(economic number) is the bottomline number where the most cheapest most efficient most lowest cost of getting coin that no one else on the planet can go below
anything can develop a store of value. even if that store of value is just a X cents.
the issue is... if the PRICE remains close to that SoV to protect majority of someones wealth from loss when they buy. or if its bubble inflated/premium far far above SoV line
(its why most PoS coins are not $1k+ and those that are. thats just unprotected pure speculation over hyped/pumped prices that are not sustainable)
EG
right now people buying bitcoin at this quarters rates have a wealth security of 75% SoV, IF!! they bought at $20k(Sov ~$15k)
where as if they bought at $60k their wealth has only a 25% SoV security
bitcoin is a good store of value because its deflationary nature means at the next market cycle that pishes up SoV and thus the price speculation window above it. that wealth stores last/this year gets more protected later..
unlike inflationary fiat where the longer you hoard fiat the less value is protected and you lose value
..
separate scenario
those buying eth at $1.5k might have a 66% Sov now(~$1k inc hardware pow). but will soon be more like 0.05% after PoS
so expect a massive price correction when fully PoS and a value protection loss of like 99.95%
as for your other comment about government..
PoS doesnt use special equipment
what you might be more concerned with if you like PoS and are gov worried is...
..is not equipment. but [inserting slight gov conspiracy theory for you] if the custodial pools (EG coinbase which is regulated and licenced) got told to seize all the staked value by regulators(hand custodial keys to regulators) or if coinbase got told by regulators to perform some task using its staking opportunities(and other regulated services told the same).
- but thats entering into the extreme realms of the line between possibility and conspiracy
a more rational concern of gov intervention is..
..is even when regulators are saying that for instance liquid, LN and monero are bad currencies which exchanges should not custodianise or offer services for.
reality is those regulators are not begging to seize all monero/ln/liquid funds. they are just saying to regulated exchanges, to just dont offer services to those currencies in the first place. thus most govs wont seize equipment/coins for the sake of it. but instead you will just see less custodians(legit businesses running pools) and businesses (merchants) accepting those PoS coins should governments take a bad eye to a PoS.
but that same rationale can happen with any 'proof-of..' coin
but to the point of store of value
bitcoins SoV grew from about $0.04 early 2010. to ~$15k 2022
eth grew to about $1k in 2022 but is about to drop to a couple dollars or even a few cents SoV after PoS
(expect a massive price correction)
as for the market prices of those coins. well thats the speculation and whimsy stuff above SoV of the times.. which is more wiggling and volatile above SoV
so just be sure to buy the LOW not the HIGH if you want to protect more of your wealth when you buy.
..
bitcoin is a great SoV because even if you buy a high. deflation means if you leave it long enough more of your wealth becomes protected as the SoV increases over time
(unless bitcoin foolishly does a PoS or algo reset or something massive to change the dynamics of economic policy)
