This was a really interesting reply, thanks. I’d leave a longer response, but honestly I really need to be asleep right now.
No problem. It’s past my bedtime too, but I’m really pleased that I’m able to discuss this stuff and I’m not getting downvotes or called a shill simply for providing information. It’s always been a big area of fascination for me, the technology is really neat. :)
You can definitely get started for $1000.
Sure, you could set up something that can process blocks. But there’s no way you’d be able to make a profit with something that small. One of the fundamental tenets of cryptocurrency is that it doesn’t rely on anyone acting altruistically, it assumes that everyone involved is in it for the money. It leverages greed to ensure that everyone “follows the rules”, by making it so that if you break those rules you make less money. So I wouldn’t consider a blockchain to be secure if it depended on miners who mined at a loss out of the goodness of their hearts. When people worry about centralization they overlook that Bitcoin has economies of scale that massively favors the bigger mining operations, the dollars-per-hash are much lower for the warehouses full of ASICs next door to a power plant than for the guy with a graphics card in a closet at home.
I did also mention that you could get involved in staking on Ethereum for much less than $120,000, at the cost of depending on third parties to handle the actual validation. You can do that either through staking pools or liquid staking. Essentially, you own a “share” of a single validator’s stake and get a proportionate portion of the validator’s rewards, minus a fee that the validator charges for actually running the validator.
The comment you’re responding to linked to a page giving statistics about the Lightning network. The number of channels peaked in 2022 and has been going down ever since then.
