I am running ETH nodes at home, on RPis. They are even participating in the (future) consensus model through PoS.
I'm a fan of Bitcoin, and I'm not sure why the random need to criticize Ethereum here. Bitcoin has enough reasons to be useful, no need to be insecure about other projects being useful too.
I was under the impression that the RPi CPU is too slow to process/sync blocks. And unless you have an SSD to store blocks, IO will limit your capacity to verify new incoming blocks every 15 seconds. This was my experience a few years ago.
Are your running a full archival ETH node on a RPI with a 3TB+ SSD attached?
Half of them are debatable and the rest is true but useless.
You gain nothing from using a system that's 12 year old over one that's 6 years old.
Also more nodes just dont add any usefulness anymore at some point, it just more not better.
Reliable is useless without comparing it to something else.
BTC had unintentional forks and many small possible double spends and all that stuff in the last 12 years. Its overall reliable, sure but at what metric. Incidents per time? incidents per Tx? Or just the fact that it didn't die in the last 12 years?
Seems pretty easy to me. What is Bitcoin best at apart from having the largest market cap?
