The world is run by the state-bank alliance. The top politicians and bankers jointly profit from inflating the values of money and debt with state power -- this system couldn't survive without either side.

The interesting thing is, if you buy and hold gold and Bitcoin for the long term, you can benefit. (Just make sure you don't buy when the global empire is rising, like the 1950s or early 1990s.) The reason is also due to the nature of the state-bank alliance.
Note that, in this alliance, the top politicians contribute state power, while the top bankers contribute financial know-how. The politicians, being totally ignorant in this high-stakes and specialized game, are basically led around like children. They just go along because they benefit from issuing huge amounts of public debt without being punished by the 'markets.'
So here's the problem with this alliance. When financial asset values collapse (and this day will come, due to the incentives faced by the elites) and everyday people suffer, the politicians will put all the blame on the bankers. The reasons are obvious (and there is no loyalty in that game,) and the politicians are going to win that argument. The biggest such events in history include the Spanish Inquisition and the Nazi Holocaust. In our day, politicians like Bernie Sanders and Elizabeth Warren have already gone after the bankers.
Knowing that, the bankers and central bankers must prepare a last-ditch rescue for a worst-case scenario, when all trust in the system is gone. That rescue will be some non-state-issued asset, like gold, silver, and Bitcoin, that the elites can peg their money to (at a high price for the non-state asset,) stabilize their system, and ease the suffering. Even if the bankers think there's only a small chance for such an occurrence, it will be so devastating to the bankers that they must prepare for it.
So, the elites will try to suppress non-state assets, but won't kill them, even when given a chance. In the long run, this presents something like a one-way bet for these assets, at current prices.
The reason why is that people always hold bitcoin is that because they actually save it from something or situation that may needed like emergencies and many people also expect for the amount of it to get higher in the future. People did some strategic way of holding it and aaiting for the right time to sell or to use it because they find it more profitable.
