I agree with this, for certain the big players and status quo do not want there monopoly removed and the new crypto systems are just that exact threat to them, this I predict will just be the beginning of a wave of moves that the banks and mainstream powers will take against crypto currencies, the people who run the world control the banks, and they are not going to give up the power they have without a fight, but the community I believe will win, because in the end we are stronger.
The thing is, as much as I see that yes, these are their first moves in their fight against crypto. I believe that they'll also 'invest', either buying coins, creating a blockchain, creating a coin, all the above; just to hedge their bets and stay on top.
Yes I think you are right for certain, they will move from different sides, they will fight it but they will also try to infiltrate it and control it, it is what they have always done with everything, I guess we need to just stay wise to that as a community and with new technology try to build in methods that can mean community control remains dominant. :-)
