IMO payment options are great for consumers. If the merchant is willing to bear the risk. Watt Wagons is upfront about the % of risk they are willing to bear.
I just googled energy usage, and this statement caught my attention - (
source)
“Energy use in itself is not bad,” Meltem Demirors, chief strategy officer of digital asset management firm CoinShares, told CNBC. “Sending and storing emails uses energy. Yet, we don’t infer email to be bad because it consumes energy.”
“What we have here is people trying to decide what is or is not a good use of energy, and bitcoin is incredibly transparent in its energy use while other industries are much more opaque.”
That is not to say that "email" is tainted (if you will).
If you realistically look at it, I would say they are
literally taking resources and converting them into currency in one step. It is much more efficient than a traditional way to convert earth's resources into money - historically one would paying people to dig up a mine, take dirt to factories, purify the gold, sell the gold and THEN put money in the bank.
So in a weird way Bitcoin is better than most stuff we do today. Lol.
