I have a question.

What will happen when the 21 million #Bitcoin(BTC) are in circulation and countries implement the digital euro/dollar/pound?

That is, let's consider the case that the monetary system fails, because nobody wants those digital currencies and we prefer cryptocurrencies and the entire planet works with Bitcoin, but Bitcoin is at €400,000 and being in circulation and limited to 21M.

There would be no Bitcoin for everyone and it would be controlled by a Whale Monopoly.

What would happen if we reached this extreme?

I am not saying that it is something realistic, nor that it is a revelation and even if it could happen it would be in the next 30 years. It wouldn't be something overnight.

What do you think?
