Why "economy"? It is limiting the definition. I'd say the network as a whole not just the economy. For example the "economy" was centralized back in 2013 when there was one major bitcoin exchange (MtGox) controlling more than 85% of the total trading volume and it was manipulating the market. Yet bitcoin was still decentralized.
It was decentralized, but less than it is today. If we're going to agree with my centralization definition, then it's true; few people who owned an exchange had a fortune of 850,000+ BTC. The manipulation was easier and more intensive than it is today. Charts speak themselves.
Economy isn't a strictly connected term with money. It's related with administration, in general.
P.S. Here is a realistic risk of PoS: a lot of people have proven to see cryptocurrency as a trading tool and they will deposit their coins on a centralized exchange. All of a sudden we have one entity with a huge amount of coins aka stake that can control the PoS too.
Don't you choose a pool to stake?
One could enter this debate, but their is little reason.
If the person supporting PoS is winning the debate, then the mods lock the topic.
If the person supporting PoW is winning the debate, then the mods allow it and others point to it as proof.
This place is known for its freedom of speech. If you don't want to try, then don't blame mods. The mods don't lock topics subjectively. Only if it's against the rules.
Of the top 12 coins
1 is PoW , 4 tokens, 1 custom XRP
The other 6 are PoS.
So no matter anyone's opinion here for or against, the marketplace has already chosen.
And their is an undeniable lean toward PoS or anything other than PoW.
Which proves what exactly? The market had also chosen to put a dog-looking coin in the third position. Is that what you want? To simply reach a certain position among other currencies? Is that your project's goal?
Their will be no green energy solution fix to the above, as China one of the largest hydro energy producers was the 1st to have banned PoW mining.
Europe could ban PoW mining by 2025.
And now you're comparing China with Europe...
The final question coming is will the world government let your PoW survive, and that is what you need to worry about if you want PoW mining to continue.
Okay, so... May I assume you didn't read my writeup, right? I've detected flaws to your mechanism and you keep avoiding them. You're the one who asked for serious conversation, troller.
Financial gains has little to do with it. If you buy ASICs from another miner, then you also increase their gains.
You do have the option to not buy them from another miner, though.
