Now the twist. 1 small country can buy all the bitcoins.
No they can't.
At current prices all the bitcoins would still be around 120 billions and a small country does not have the GDP close to that, not talking about the budget which is usually around 1/3 of that.
Let's say that they are indeed planning to buy them, how will the market look after a 100 000
BTC buy ?
The price will probably shoot up to 20 000$ at least , making the remaining bitcoins double in value.
And by the time they will manage to acquire 1 million the rest will be probably worth 1 trillion.
We can even make our own prices if all miners agreed to sell 10k only price will be 10k. 100k only 100k.
Oh, so you mean transforming bitcoin in a cartel with fixed prices.
Forget demand and offer, forget free market , forget everything. WE WANT MONEY!
The moment that happens (I pray it won't)
BTC is doomed for sure.
