I think it's kinda like oil and the people that have previously designed alt fuel cars hydrogen , elect , water solar ect all to be bought out by the big oil companies, but now we have chewed thru about half the planets oil in like 100 years, well hybrid and green fuel cars are given the green light.
I know oil is a resource and different to currency however, people power is speaking up and people dont like being controlled anymore, the US deficit is gonna have major impact world wide, we need another currency, just like we need alt fuels, and i recon the powers that be know it, so it's hard for them to implement any laws to outright kill crypto currencys, because they need it as a backup not to mention I bet half of them love trading fee free, I wonder how many banks use it to transfer funds one day saving tons of cash then the next day outlaw it lol
