Each crypto is a type of tech stack that runs on the decentralized "block chain" / "ledger" which is just a giant database spread across many corporate and end-user computers. They use fancy words for database and other stuff, which is intentional for the marketing scam that woos new people into the hype.

It’s not a database. A database is a centralized store of data which someone ultimately has the power to change at will.

The blockchain is distributed, and no individual person can rewrite it. (unless they control computing power equivalent to 51% of the total computing power of the entire network, which is not easy to do and gets harder by the day)

The key technical innovation here is having a distributed system of record keeping that does not rely on any individual to be trustworthy. You can read the paper for the technical details because it is written in plain English.

It can be controlled down to the single resident living in an apartment with a smart meter; they can disable your power remotely with the flip of the switch...smart grid indeed. Just try thinking it out a bit further.

That’s not how it works. Yes they can track your energy usage, yes they can shut it off. No they cannot know what you are doing with that energy. Yes it is easy to mask.

It is a serious energy hungry thing (virus to say the least) and requires a big government grid to operate. It is consuming microchip supply like crazy, GPUs and CPUs are being first-classed to crypto mining farms with plebs getting the short end of the stick and last gen's hardware, it's fucked. Crypto is not possible without the type of energy grid that BIG government offers.

You haven’t done enough research because you seem to believe that Bitcoin represents how all cryptocurrencies work. No, not all of them consume large amounts of energy the way Bitcoin does.

The entire crypto market is pinned to Bitcoin even though BTC itself is not the most optimized of them.

That’s because BTC is the original and most trustworthy one. It’s the same reason people tend to prefer name brands over similar generic drugs.

I'm an early investor. Still do your research.

I’m a computer programmer, I’ve done my research.

It's easily manipulated and controlled by governments. They can simply ban it. Or tax it. Control the exchanges, etc.

Name something that isn’t, other than God lol.

And it's a giant pyramid scheme with the first many hundred/thousand Bitcoins unaccounted for (held by an unknown party).

Those things do not logically follow. Many cryptos openly reserve the first X amount to pay for continued development. Do you expect people to do all this hard work for free? It doesn’t hurt the integrity of the crypto if the founder holds some for themselves. The critical thing is that the supply of crypto is fixed and not manipulated, because then nothing would separate it from fiat currency.
