My opinion is that Proof of Stake is better than Proof of Work in the terms that you don't need to own an ASIC miner nor even need to use CPU/GPU power to get new coins. I also think that this makes it more energy efficient. Please correct me if I'm wrong.
Looking forward to your comments. Thanks
Lets say you have Hyperstake that has a 750% interest/year that would say if there is 1M coins in circulation the first year it would be 7.5M the next year and 56.2M after only 3 years!
So lets say that the marked value of each coins is is 1USD so the total marked value of the coin first year would be 1M (just to make it easy). Then you would need 6.5M USD in the coin just to keep the price at the same 1USD/coin. the next year you would need an extra 49,7M USD to keep the price at the same level!! this is insane much money before the price even begin to increase.
But yeah it is very energy efficient since you dont need big rigs
POW you need much money to start getting into the coin mining, and electricity cost sucks.
But it creates alot of "jobs" for people. Like people who creates hardware - hugh farms and much more.
Personally I like POS best, but not with more then max 10% interest year.
( If I said something wrong correct me please )
