All systems use numbers to express the quantity of shares in a system that someone bought. But in the bitcoin system these shares are worthless because their holders are unable to return their investments from the system that issued them.
I am still not sure whether you truly don't understand or if you are just pretending. Bitcoin is not a system of "shares" like in traditional stock markets. Why do you keep comparing them?
To put it simply, Bitcoin is merely a method of transferring value between two parties. P2P type of payment system. There is no issuer of shares or company in which you invested funds when you exchange fiat currency for cryptocurrency. You simply exchanged one currency for another while, at the same time, someone else did the same in the opposite direction. That is it!
You don't get it, do you? Whatever you say about bitcoin it won't change the fact that people cannot get anything from the bitcoin system when holding the record of how many shares in this system they have. People invested in this system, got the records or evidences of their investments, and then they are able to return their investments only if new investors buy their records. The system returns them nothing, it is completely worthless. That what you call bitcoin is just the name for one share in that worthless system. Just like one share in the US dollar system is called a dollar. When people invested in the US dollar system and consequently hold dollars as evidence of their investments (shares in the system), it is this system that returns them their investments. Either through goods, services or labor of the borrowers or their collaterals if they default on their loans. The bitcoin system is a scam that lures people to invest, and then leaves them with nothing, which is why they are forced to wait for new investors like in all investment scams.. Your writing is just marketing for the bitcoin scam. People are not transferring value through the bitcoin system. That's a lie of the bitcoin marketing. They are transferring records of how many shares in the worthless bitcoin system they have. Stop spreading lies and disinformation.
If you have the audacity to judge what is a „scam“ and what not(while having 0 knowledge of it), then go ahead and give us examples of things that aren’t scams compared to Bitcoin. Im waiting, but i already know you can’t.
