its simple
at a PC rating of 100w (2.4kwh a day) = $180kwh in ~75 days. means
at $0.04/kwh thats a $7.20 cost for waiting 2-3 months to get 2ethereum on PoS or $3.60 per eth
yep
when they say that eth2(pos) is 99.9X% less energy intensive than PoW.. what they are hinting at is the cost of creation is X000x less costly. so expect a X000x factor decrease in value and thus an effect of a X000x factor of price speculation crash too
You are leaving out the fact that you have to spend time to keep your client software up to date. And that you are leaving all that eth locked up.
(i say all this in humour. not as a argument. so smile while reading it. its not a fight)
hey if you dont like my pencil math number of about $3.60/eth.. then try your own math out.
add in your own variables. set your own valuation. im not the cost controller. im just giving example of pen and brain math for easy demo..
but hey even ethereum themselves are highlighting their 99.95% less energy usage (cost)
..
i was just doing some pencil and brain maths, even if i dont explain it all
400k validators at 6k blocks a day is ~66 days. so guess why i rounded to ~75 days .. mhm. yep i included the initial block download and other factors and 75 seemed like a good buffer round number to use instead.. and so i didnt stick to the 66day number (which would have been far cheaper)
heck i didnt even use rasberry Pi possible lower costs. so i think its a fair valuation
point is though in normal daily cooperative function of good mining of both PoW/PoS. costs are 2000x difference. causing a 2000x difference in underlying value.
when talking about "good miners" the penalties dont trigger. so i was going with the good miner cost scenario(les variables to wall of text about. trying not to wall of text waffle all variables etc was me being considerate for once
the point being.. and why i even mention ethereum. is they are going through this very scenario right now
the general
cost of not malicious-no bug, no error no reject no penalty trigger mining is a 2000x difference. heck even ethereum are picking up on that point and using it as part of their advertising strategy with their 99.95% energy usage(cost) reduction
you can spend hours trying to calculate other costs if penalties are triggered or blocks are rejected in both PoW and PoS
oh and we could have long debates of walls of text about other factors.like
how most of that stake is not actually on 400k pc's where each pc waits upto 75 days from its startup. but instead staked on exchange where its 1 exchange node doing the block signing on behalf of thousands of stakers who dont have to IBD or stay online 24/7
like how its not everyone waits 75 days as some might be lucky and sign multiply blocks within that time and some may wait longer. but hey its an average.
but hey.. the exact refined amount to the penny amount is not the point its the general point of being "a heck of alot cheaper to mine" causing the value people are willing to sell at be a heck of alot less
even ethereum are using the "heck of alot cheaper to mine" when they are promoting the 99.95% less energy usage than PoW..
(separate detail unrelated to the 99.95% energy/cost /value stuff.. and more about the security lacking of PoS)
oh and i also hinted at one of the FLAWS of PoS (staked on exchanges) where those exchanges also being a needed service in of itself as a gateway to fiat and merchant tools. becomes an influencer of blind following where people end up following the whims of an exchange just to stay on the fork the exchange wants to be on so they can still work with an exchange.. and ofcourse not want to lose their stake at the same time if they did fork away from an exchanges proposed blocks which becomes a double penalty for the customer(not the exchange) if the customers want to go-against a exchanges whims.. . thus giving exchanges double influencer/power of network control.. but shh thats a whole different debate for a different topic
