So you don't think the major banks, governments and central banks have no problem at all with a rival monetary system that they can't regulate, control, tax, monitor? So their fractional reserve system is in no way threatened by a decentralised system.
And also you miss the point that IF Major banks and central banks get involved in starting currencies then they will want to control them and have back doors set in place.
Central banks will have a huge problem. Investment banks will have no problem. It's basically one more unregulated pile of money for them to profit off of. Why would they give a hoot?
Investment banks have as we know a symbiotic relationship with Central banks. The revolving door at the FED is well known and the FED was founded by major banks like JPMorgan etc.
I know it's ok to have a different opinion to what I'm saying but I don't trust your account as it was only opened just and so far You have only dedicated you involvement on this site to counteracting with no real substance the idea that Banks wouldn't be concerned if a bitcoin went mainstream, which is obviously false.
