So how are you a shareholder in a medium of exchange? How would that concept transfer to currency, which you want BTC to replace? You're all over the board here.
But how does that alone create value to the thing itself? Near as I can figure, you're conflating an infrastructure for exchange with the value of the thing being exchanged. And so how does that profit you as a "shareholder?" Because some whales bumped up the price?
Wait. So is BTC the bank or the thing stored in the bank?
Yes, if you own bitcoin the digital asset, you are part owner of the Bitcoin monetary network and bitcoin is traded on exchanges all over the world as well as p2p markets, i.e. restaurant in Lugano or a vegetable market in Turkey
All of the Bitcoin miners and their infrastructure costs and operational costs exist for bitcoin the digital asset
If you bring up imaginary whales as your argument, then you have to look at your motives
Yes, Bitcoin is a bank, when you buy bitcoin using your fiat currency, you have effectively opened a digital bank that you take full ownership, no need for custodial intermediaries, you simply store in your own wallet
This is one of the reasons El Salvador presented to their lawmakers that over 70% of the population was unbanked even after decades that banks have been there
You're getting overwhelmed by the many use-cases of Bitcoin and you try to paint them in the negative. Bitcoin the digital asset can be used as MoE, but also as investment asset, but also a transfer of value mechanism across borders instant settlement and for low costs and many more
