Actually I think the biggest enemy of BTC are these players with huge amount of fiat capital, although BTC was designed to be a currency free of central banks manipulation, it still could be manipulated by the powerfull players in the market
Here's my two cents. Pun intended.
Who says those greedy bastards don't have their grubby little fingers in it already.
Banksters are your enemy. For now they are our asset to gain the BTC.
I fear the banksters manipulation on the market itself...I mean they do control their money.
What I don't fear is the inevitable market bitcoin can provide.
It can and does provide(s)...black market, free market, food markets, product markets, and becoming your own bank without a teller is great.
Sooner than later you will see less exchanges and more markets...
The day you pay your electric bill in bitcoin is the day banks are destroyed by the people and for the people.
I eagerly await that day.
