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.
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.
Spanish Inquisition was merely the result of politicians' activities and was targeted at ensuring the "canonicity" of the faith of converts, especially Jews and Muslims forced to accept Catholicism.
It had nothing to do with the bankers, as in the 15th century there were no "bankers" in the truest sense of this word.
The reasons for Holocaust (if you mean the genocide of Jewish people between 1941 and 1945) are more obvious as Jews became the most prominent financial players by then.
Nazi's aim was to exterminate all the sprouts of independent and successful management of finances so as to take the obedient German nation on a course needed by Adolf's government.
Today the situation is different - everybody can choose his own way of earning money, nobody can prevent you from investing in BTC, or gold/silver, or whatever.
The only thing one should do is do his own research and monitor the news and prices (which is not very hard in this era of Internet).
