This emoji summarizes it perfectly: 🤢
There are some valid points here, and I agree that the energy could be used elsewhere and that green energy is not entirely green.
I even agree that for most cryptocurrency as they are now the cost per transaction is higher than alternatives. However the technology for cryptocurrency, especially with PoC can be a lot more efficient in scale. To get an idea of it you can look at Visa, which processes 1700 transactions per second, BCH can do 178, so 10% of it, ETH2 is supposed to be able to process at least 20k, so 10x that amount. I imagine either of those coins pollute a comparable amount to visa when you consider everything that visa needs to operate (machines, cards, servers, etc). I feel that people don’t take these sort of stuff into consideration when they talk about the energy consumption of crypto. There is a discussion to be had here, but blankly stating that it’s an environmental disaster is fear mongering.
Visa can process a maximum of 24k TPS
Crypto energy usage goes up the more it’s being used and the more decentralized it becomes. Centralized services like Visa can increase the network load while barely increasing the energy requirements.
Crypto bros always forget that to replace the banking system, crypto would need to replace the infrastructure as well, but because of decentralization it would be less energy efficient for the same result.
You can just stop, there’s no way to greenwash crypto and decentralization. The amount of transactions happening on all crypto networks at the moment could be handled by one server if it was centralized. There’s benefits to it, stop trying to sell it as being green, it’s not and never will be.

That’s wrong, crypto energy consumption has to do with how hard is the PoW difficulty, it does not correlate at all with usage or centralization, it’s only related with security, i.e the more energy it consumes the more energy someone would need to use to attack the technology.
But the energy needed to mine 1 transaction or 1000 is the same. There are problems at scale, but power consumption is not one of them.

Not really, they need more servers to process more transactions, but cryptocurrency can scale up much more easily because the whole infrastructure from consumer to miner is decentralized.

That’s what most people fail to see, the infrastructure for a scale at the size of visa is already in place for crypto. So there wouldn’t be an increase in power consumption by mass adoption, only by miner adoption, and that’s a difficult thought to grasp, it’s like if everyone could borrow their computer to visa or Mastercard to process their transactions, the amount of people wanting to offer their computer to visa/master would define how much resources they use, but an increase in visa users doesn’t mean an increase in visa borrowed servers and vice-versa.

I’m not trying to green wash, but crypto is not the environmental disaster the person claimed, especially not when you take into consideration PoS and newer coins with different validation methods.
From the get go, you’re wrong

The more people mine, the more decentralized it is, the more energy is necessary because difficulty is increased. The more transactions happen, the more blocks are required, the more energy needs to be spent to confirm all the transactions. The more it’s used, the higher the value, the more people mine.
There’s a limit to the number of transactions per block as well, so no, your can’t just say “1 or 1000 it’s the same”.
Visa is already able to handle 24000 transactions per second as is, no need for more infrastructure.
Crypto uses 1% of the world’s energy production for a couple trillions in assets, the financial system uses 2.5% for quadrillions in assets, multiple thousands more than crypto, no, crypto can’t scale to that without a huge environmental impact.
Yes you are trying to greenwash crypto, just stop.
