8:what will be the fate of government and world banks if cryptocurrency take over Fiat and fully takes control of the new money?
History has shown that bank owners have been hung repeatedly. If crypto only pushes their fraudulent system to light I find it inevitable to occur. as for "government". My view is that it is no different than Santa Clause. It doesn't exist as real rntity. However shifts of power among those that call themselves government will undoubtedly occur.
Once the many outweigh the need for fiat they will want to be more chained to crypto. howver I dont personally see crypto as a means to "save the world" from the clutches of greed, poverty, and evil men controlling this earth.
Only self knowledge of who they really are will help with that. IMO
I noticed too because whale manipulate market to accumulate more.project builders accumulate what they create and dump it on investors who invested on it.
Many illegal activities has happened due to crypto.
That's the world we are in
The only thing cryptocurrency gives very much is security and freedom but cryptocurrency didn't stop greed as you said didn't stop poverty but solve some but can't eradicate poverty from this world.
