I know there were a lot of "advices" from people with their opinions how to "save Bitcoin". I have decided to write that mine anyway.
It seems like central bankers are making swings in price of Bitcoin to discredit it. In my opinion it is the only tactic but effective one they can use if they want to fight Bitcoin. And there are plenty of reasons for them to do that. They just pump and dump huge sums. You can spot them when there is a buy/sell at MtGox at round numbers. Let say buy 5000 bitcoins at 75.00.
With these swings bitcoin will remain just for speculation only and no use in the real world. Because who wants to buy bread with 20% different price every week. With no use in real world (I don't mean SilkRoad - that will stay), there will be no value of Bitcoin in the future.
So my advice is: Try to engage as many people in buying Bitcoins as possible so the bankers/forex traders would have less and less power over this amazing currency.
