yep windfury is correct and its why vitalik decided to call the smallest eth unit a wei many years ago, as he was always favouring/inspired to go the PoS route and follow the path of wei-dai for years, he just had to use PoW for eth first to create a community of interest due to PoW's good value policy(which PoS doesnt have). so he had to snare greed/value interest of people first to build the community before converting the community to vitalik long plan wishes(wait for the market speculation correction DOWN when he finally allows the code to un-stake)
Part of the reason (maybe the main reason) is that Ethereum copied a lot of its ideas and implementations from bitcoin, which means the mining algorithm (PoW) was also part of it. In fact Vitalik was once hanging out in bitcoin circles trying to convince us to destroy bitcoin's smart contract protocol and make it vulnerable like how ethereum's is today. He failed so he created the shitcoin we know today as ethereum.
correct he was part of bitcoin but found out early on that butting heads against he core roadmap and treated like an attacker rather than a proposal suggester. is where the centralisation was first spotted and the clan cultish mindsets began
funny part is.. ethereum has its subnetwork bridges and more people are prefering to lock bitcoin. and use as reference point to then play on ethereum subnetwork bridges. more so then using the failing subnetwork bridge that was promised as the solution to bitcoin scaling
the bitcoin scaling solution of a sub network bridge promise made 7 years ago. has less users less liquidity, but more flaws than a ethereum subnetwork bridge which is only 15 months old
im not suggesting ethereum is better(for may other reasons). but more users are preferring to avoid the offering by the core devs.. because core devs seem half assed in being devs and more inspired to be sponsored governors/moderators ensuring they stay in power
and yes a you can do your own research and finds the stats.
