Actually it’s just my own vision of things but of course I don’t have a crystal ball to predict the future. Nevertheless, I based my analysis on few relevant informations for instance, Ethereum is now a green blockchain i.e. it now requires very little energy to run a proof-of-stake validator. For instance, one server/validator is using around 50 watts per hour of electricity and on that same machine you can run several validators without much electrical input increase. I know because I presently run one server with 2 Ethereum nodes on it. All the proof-of-work cryptos you can mine with GPUs are energy-intensive which is bad for the environment plus with the actual energy crisis it’s not interesting.
Also, it’s important to see the usage behind these blockchains. You have to check the active addresses on a blockchain and the decentralized apps being used. In my opinion, Ethereum is the future with few interesting competitors like Solana or Cardano and they all use proof of stake consensus mechanism to approve new blocks. My brother is a back-end engineer working for a crypto company and he confirmed me that the vast majority of developers are presently coding on the Ethereum protocol. On the cryptos you can mine with GPUs, there’s not much activities. Go look on GitHub, you’ll see there’s not a lot of developers working on proof-of-work cryptos.
The cryptos running on proof-of-work which could be mine with GPUs don’t have much real usage other than speculative investment or store value. GPUs can be use for machine learning but if there’s no lucrative solutions at the end for miners then they won’t get good traction other than researches.
Go check EthereumClassic TVL - DefiLlama
there’s just $308,043 of total value locked (USD) in Ethereum Classic, there’s no decentralized finance applications really on ETC. It’s mostly speculation of store value which will probably fade away with time. GPU crypto mining was working because before the merge we could mine ETH, not anymore.
By the way, with the actual ETC price you have to get electricity cost at 0.01$ kWh just to get even. It seems in Norway electricity is almost free.
