I fully agree with your disappointment, mine is the same. However, I think that the problem - in as much as it is a problem, which it seems to be to you, and it is also to me - that bitcoin and the other crypto currencies are mainly speculative assets ("bricks of gold") and are not so much a payment system after all,
is not due to "the community betraying Satoshi", but rather, that it is a fundamental design error in bitcoin. At least, if Satoshi didn't want it to become a speculative asset, but a payment system.
What turns bitcoin by design into a speculative asset, and what makes it impossible to become a good payment system, is the emission curve of bitcoin: the fact that bitcoin was created a lot when it wasn't worth much, and has a decreasing supply when there's an increasing demand and adoption, even making this supply drop to zero. As such, you get early adopters that enjoyed HUGE amounts of seigniorage, and could become rich with very little risk, investment, and effort, while having something whose increasing rarity is boosting the price. It makes for great stories of getting rich quickly, people not wanting to miss the train, fear of missing out, .... everything which makes for the better greater-fool game.
Bitcoin has been advertised from the start as "you know, there will only be 21 million coins, if this is going to become the worlds' money, can you imagine how much one coin will be worth, so buy some now for a low sum and be wealthy in a few years !"
The "limited amount of coins" and the wealth of a few early adopters has made bitcoin into a "get rich quickly" machine, not into a "good stable payment system". Sound money theory with huge initial seigniorage (an oxymoron in itself) is the flawed economic model of bitcoin, instead of Nash's ideal money theory. It is a flawed theory for a payment system, but it is the perfect design for a huge greater-fool game, also known as a pyramid scheme, which is what bitcoin became - because it was designed that way.
Most other crypto has the same design flaw, which turns this whole thing into a joke as a payment system, but which turns it in one of the better financial gambling feasts in town. And pumping, it will ! Visibly, financial institutions have too much money on their hands, and have been restricted by law to gamble. They are longing to be able to gamble on crypto, and this will be the origin of the next big financial crisis.
I'm writing this post because I see it everywhere on this forum. People who just talk about Bitcoin pump(s), $ price, € price and so on... even most legendary members do it!
I think most Bitcoin users miss what Bitcoin really is and what Satoshi wanted it to be.
If you read the white paper, there's no mention about Bitcoin as a digital asset. Satoshi just wanted to create a payment system, a strong one and much better than the traditional ones.
But right now, Bitcoin is mainly considered as a digital asset, digital gold, just an investment tool to make (quick) profit. That's wrong, in my opinion.
I think Bitcoin users are raping Satoshi's original view, thinking only about BTC's value on exchanges.
What most don't understand is that Satoshi gave us a huge power. The power to destroy and make disappear forever the whole old banking system, other online payment systems like paypal and maybe governments too. Forever.
He gave us the power to decentralize everything using the blockchain technology. In short, Satoshi gave us the power the change the world for the better.
So why are you focusing only on Bitcoin's price on exchanges?
Imagine this.
A world where you can send money anywhere and to anyone in the world, instantly and with low fees.
A world where you can buy anything using Bitcoin, from coffees to yatchs.
A world where you can get all the privacy you want.
A world without banks.
A world without old currencies, that only create inflation.
A world where you pay only the taxes you wanna pay and not what you are forced to pay.
I think Satoshi's original view was very revolutionary.
A decentralized payment system and a deflationary currency. A real digital cash.
But now, Bitcoin has becomed just a digital asset. Maybe a toy for rich people to get even richer.
What's so revolutionary about it? The world is already full of assets and investment tool...
In short, Bitcoin lost most of its revolutionary appeal.
I strongly suggest you to change your consideration about Bitcoin. Now it's time to choose, because what we - as a community - decide now will influence all the future history of Bitcoin.
So, what do you prefer? A brick of gold or a better world?
