You are ignorant. Crypto is basically a speculation vehicle for the wealthy venture capitalists and other wealthy charismatic let's jump on a trend bros, backed by nothing but their whims.
You are tools, Greater Fool theory. It's funny to watch it play out.
I mean I don't like the control the wealthy have on society with government, but at least they provide some substance to their crookedness with a functional currency. Crypto is a ponzi scheme, and that's way worse.
It's really funny to see you talk about a bank run in Greece when look at the fucking instability of crypto that you just totally ignore. It's pathetic.
I don't disagree with your first point and it is eactly why crypto prices fell. because the large investors always pull out of the most risky investments first. But it isn't either or. It's like buying shares or investing in a start-up. You assume their vision and hence future products or services will sell well. So you invest. Just because you don't believe in the idea, doesn't mean everyone else that does is a fool.
And yes like with any start-up, there is a huge risk involved. And there is a fine difference between investing and speculation. Speculation means to me that it is only about making profit and not the "vision" or "idea" behind the project. But it is only a semantic difference as in both cases what you do is buy coins.
The thing is the current system is also a Ponzi scheme, with hurdles so that it isn't plain obvious and more stable/durable.
eg. fractional reserve banking. You can just search for it if you actually care about the truth.
So why wait for your country to collapse, when you can put your money in ponzi crypto coins and live every day on the edge of doom?
That isn't a strong argument.
Also note that while Greek Economy collapsed because it was completely unsustainable, the currency DID NOT collapse because it was a stable and resilient Fiat currency backed by the economies of the EU.
It's not an argument but an opinion. Just because you trust so much in the US government by their secret overlords, then yes, it makes little sense to not but all your money into the traditional systems. On the other hand diversification never hurts, so having stocks/ETFs and crypto isn't entirely stupid idea. And yes it is a stupid idea to but all your life savings into crypto.
Greece didn't collapse because it would have been embarrassing for the EU and the euro. So they bailed them out. just like banks get bailed out. See if the banking ponzi-schemes starts breaking apart they take the tax-payers money to fix it. The core issue with Greece was and still is that it simply doesn't work that countries with very different productivity rates (eg Germany vs Greece) can have the same currency. As long as Greece had their own currency they could always offer things much cheaper than German competitors. (there is a documentary about this somewhere. I don't remember the name and it might not have been in english)
