I agree with you, It is worthless. A medium of exchange is only valuable as long as there is a taker, being a fool or a smart man, depending on the price.

Everything is a ponzi scheme. The visibility of duration, conveying the idea of stability, is fiction. So, there is always someone holding the bag.

That said:

I have detailed a couple of point in which specifically Bitcoin is totally dispractical.

SSD prohibitive: bitcoin raw: close to 600Tb and exponentially growing.
Syncing first time takes an awful amount of time
Avg mining difficulty in not even 4 years from 17T tot 85T makes it cost intensive.
Hence, co-opted by just a couple of miners, 2 have 52% of the capacity, defeating the purpose of the coin.
It is expensive in execution.
It is slow in execution.
It is totally open.
It is co-opted by the system. Wait till the full force of paper shit bears down on it. See Gold/Silver. 68 billion volume = 15 billion in derivatives.
Exchanges are fucking you whenever they can: AML + ATF, KYC, and what not.
It is a speculative volatile asset with 1 use case: get shafted.
Added on services to achieve privacy make it complex and expensive.

However, there is tons of money to be made with it. Of course, after it is exchanged for other assets ....Like XRM, lead, gold, silver, real estate, production capacities, consumables.

I'll add one more: Brics crypto. So no, BTC will not be a GLOBAL reserve currency, perhaps a regional (not necessarily geographical) one at best.

That said: we are in a transition period, and perhaps the one can for the time coexist next to the other.

The question is always: who controls the money supply. And the system in place right now, is built on the exploitation of those not knowing what they are doing, or should be doing.

A world: upside down, Davy Jones locker.
