You don't get the actual topic man, the thing is how POS is better than POW and since POS is already a good algorithm why do need need to waste energy to mine POW coins since POS is a simple solution and I do agree that POS has upper hand because no matter what but energy and resources are being wasted in POW indeed.
Bitcoin remains the dominant cryptocurrency for good reason --
POS is widely viewed as insecure. Ethereum has delayed their transition to POS by several years and backtracked to a hybrid POW-POS proposal because of the threats.
But, to buy those hardware you need to invest money and like you said if someone grabs a big number of coins they can control the network similarly if someone has a lot of coins they can sell off buy miners and actually be a whale too.
Aside from cases of pre-mining or insta-mining large stakes, exchanges remain the biggest threat to any sort of POS system:
No need to imagine, it's already been done -- at least with Delegated POS.
https://twitter.com/VitalikButerin/status/1234522463129800709Poloniex, Binance and Huobi were caught staking customer STEEM and using it to attack the existing DPOS consensus. They've done a pretty good job of brushing the attack under the rug, but the evidence is rather damning.
POS hasn't been solved yet. It may never be. POW is the best we have, for now and the foreseeable future.
These risks don't exist in Bitcoin.
The risks don't exist in most PoS coins, since PoW supporters seem unable to read anything not written by Greg Maxwell.
Greg Maxwell promote a Nothing at Stake Myth saying all PoS coin would suffer from multistakers staking on multiple forks ,
and the entire reason they would do this is an attempt to steal the majority of transaction fees.Here are three major reasons that is bullshit.
1. So far no one has bothered to even write a multi-staking client.
(Been over 6 years since PoS was introduced.)2. All stakers have to use it for it to weaken a coin's security.
(One Large Staker not multi-staking would outstake the multi-staking dummies.) 3. Any PoS coin using a design based on Sunny King original design , Destroys all of the fucking transaction fees.*Their is literally nothing a multi-staking client can do but waste your personal time,
write one and see how useless it is for you.*
Making sure the N@S myth is just a nonsense story to mislead the people that don't actually explore the PoS technology.
Proof of Stake is Superior to Proof of Waste at any day and at any time.
Proof of Waste Miners go bankrupt all of the time due to excessive waste,
Never Once have you heard of a Proof of Stake Staker going bankrupt due to the cost of staking.
Energy Efficiently counts,
do you run a 120 watt light bulb in your lights
or 12 watt LED bulbs that give off just as much light,
without wasting all of that energy on wasted heat.
So why would your want your PoW coin network to waste the energy required by entire counties,
when a PoS coin network could offer higher performance at lower costs and use so little power, no one would notice.
FYI:
As far as exchanges go, anyone giving their coins to an exchange is giving control of those coins to an exchange.
Exchanges could profit more by stealing the coins and reselling somewhere else and closing up shop, instead of trying to control a network.
More profit in stealing coins , no matter PoW or PoS coins .
