I suspect you are right about their desire but whether they are able or not is an interesting question.
Reminds me of Animal Farm, George Orwell. The people (banks) run the farm, then a revolution allows the animals to run the farm (crypto) but then the poison of power and thirst for more caused a few minorities within the animals to corrupt things worse than before.
Hopefully not. But i do see a lot of insider trading, market manip, pump and dumps and crap scam stuff.
It depends on us . If everybody decide to trade goods and merchandise in cryptos then it will bring end to Banks .Crypto is becoming more popular everyday . It will take 20-30 years for complete mass adoption . The currency war will be ugly . They will use all their power to crash crypto but there are more than 1500 cryptos . They will destroy one , but other will pop up !
