So you noticed that, too, huh? Those bitcoin ideals went out the window about $6000 ago. I think that a lot of the core believers/first adopters of bitcoin probably still cling to those ideals. But most people involved in bitcoin now are here to make (fiat) money.
As long as you secure your own bitcoin, it's one of the safest investments you can have. I worry more about losing my bitcoin (sending it to the wrong address, forgetting my passwords, etc.) than about it being stolen.
We can't say that bitcoin is always in bubbles because no one can control its price. Yes it is now in bubble but it doesn't mean that it will not stop climbing. As the day goes by, different prices changes and we don't know if people still continue to use it or leave it. I believe that the bitcoin price is only depends on the number of people who join it and work hard for it.
