Sorry, but this looks like a completely uneducated opinion.

There were many attempts to create virtual money which cannot be shit down, and all of them dated before Bitcoin failed due to government intervention. Bitcoin solved that, and the simplest solution was the wasteful proof of work.

Of course, when someone is using the same principle for something centrally controlled, which can be done by a database, that is a different story.




You know, my first foray into the world of Big Corpo people was when I met this guy studying at <pretentious arts uni in London>.

He was looking for ways to use blockchain to help regions with unstable currencies. Well, he was doing his Ph.D, actually on that topic.

So he would approach people and suggest they all meet up and have this think-tank somewhere in North London.

Now imagine you've got about 20-30 people sitting in the same room: and they are all engineers, regional managers, financiers. Not a single person has _any_ idea what blockchain is.

They were all meeting weekly to have this hours-long discussion about how they could possibly apply this thing blockchain to solving issues in the third world countries.

> There were many attempts to create virtual money which cannot be shit down, and all of them dated before Bitcoin failed due to government intervention. Bitcoin solved that, and the simplest solution was the wasteful proof of work.

One of his ideas was to create virtual money. But they forget that _secure_ proof-of-work-based money would require the same amount of initial investment (mining hardware) as if you simply went and bought several tons of gold and then issued a currency supported by that gold.


Bitcoin didnt require initial investments of mining hardware, initially it was mined with normal computers. Mining hardware is more like a running cost that goes up with usage/value.


The specialized mining hardware is a red herring.

The security of the Bitcoin network isn't a function of its hashrate or the number of nodes, though these things correlate; it's a function of the cost of running it.

Regardless of whether the network is run on specialized hardware, old desktops, or TI-83s, the network is only secure so long as it costs enough to run that any motivated attacker would have to spend more money than they can leverage to attack it.


There is even a site that tells you how much money you'd need to run 51% attacks on different cryptocurrencies. (It looks like the site used Nicehash payouts as a data point but Nicehash is down/being updated so those values are no longer there, but I found an article with a screenshot from May last year.)

Sure, if you want to do that, Bitcoin is one of the very few working solutions that have been found.

But do you actually want to do that? Who are you providing a service for by doing that?

We know the answer: Scammers and criminals, by and large. Everyone else is better served by a centralised service.


I know a handful of people who benefited a lot from Bitcoin by just speculating with it. They got wealthy, some even rich and now they have much better living standards. That group fits into the niche that were quite well "served" by Bitcoin.

Just pointing out that "scammers and criminals" is clearly not the only ones benefitting from Bitcoin, and I would suspect it is also minority.


And where did that wealth come from? Other people's trading losses.


So now the stock market is a scam too?


Stocks pay dividends. Cryptocurrencies don't.

Commodities can be sold and consumed for some real economic purpose. Cryptocurrencies can't. It's like gold except you can't see it or make jewellery from it or use it for anything.


I made no comment(s) on your above mentioned points. I was replying the assertion that "trading gains are someone else's trading loses".


It's an arithmetic consequence of there not being any intrinsic return. The money won from cryptocurrency trading can only come from other traders, because there are no coupons, dividends, or physical deliveries.


The stock market is not because good companies really do become more valuable by doing real work. It’s not zero-sum.


I don't know why this has been downvoted, it's basic economics.


Yes, not scam, but there is none which returns something back to the society. There is therefore no use case.
