Seeing as the world governments has opened their eyes for crypto,
and now cracking down on ICOs, exchanges, and crypto in general..

I fear that crypto already has been breached, and is controlled and manipulated by the 'banks'.
Since crypto is theoretically unstoppable, instead of fighting against the system, they could simply have obtained a large amount and
can keep the price controlled, and never allowing an outbreak bad enough to damage their system?

with 'banks' I'm referring to the banking industry/very rich people in general, who one way or another
profits from the current economical model, often by being middlemen, or 'earning money from nothing'.

By ruining the reputation of bitcoin/crypto in general, the average person would likely never touch it.
If p2p currency ever was adopted worldwide, it'd be a huge change for the current economical model, which of course, many top players wants to prevent.

What are the things that could happen? What are the alternatives?
Creating a new currency wouldn't work, if we assume that the banksters would be aware of it and therefore they could get a controlling part of it.
So we're 'stuck' with bitcoin, and can only hope that the coins itself are spread enough to not be controllable?
