Very simple.
Imagine you earn/inherit/have a lot of money.
(A LOT OF MONEY = POWER)

Due to it being unsafe to keep it at your home you have 2 options.
A: Keep it in the bank.
B: Keep it in crypto where you control own private key.

We live in a world where GLOBAL ELITE EXERCISES MONOPOLY ON POWER.
When you have a lot of money kept in the bank you actually have NOTHING because your access to "your" funds is not unconditional.
Just take a look at Bill G****s, do you really believe genuinity of transformation into humanitarian superstar ?

B is an obvious threat.
And threat to them is a tool of liberation for us, great majority of mankind.
