As a world, we shouldn't be encouraging the use of a currency which is literally churning out CO2 into the air when there's so many less wasteful cryptos out there
The less wasteful cryptos are more centralized. What's the point of using an inefficient data structure (blockchain) if you are sacrificing de-centralization in pursuit of gaining efficiency? Over time miners will move into renewable energies as the price of them goes down.
From a financial trading/pricing standpoint, I'd say bitcoin is centralized too, in that binance, bitfinex, coinbase and the rest of the major exchanges are necessary for the trading process.
Then when you add their dependence on centralized stablecoins like Tether to the mix, I don't think BTC would have the price it has now, if it were truly decentralized.
