Not trying to be cynical about this, but: You want nice things, not bitcoins and not dollars.
Currently, more market actors accept dollars (or Euros, or JPY, or UKP) than bitcoin, hence you're closer to the things you desire if you have dollar liquidity than if you have bitcoin liquidity.
Investments, on the other hand, should be neither in dollars nor in bitcoins, because dollars have inflation and bitcoin is too volatile.
If you truly believe in Bitcoin, you believe that a) there is a good chance that in the future USD, JPY, EU, UKP et al. will be worthless relics, ornaments in a history museum that schoolchildren laugh and joke about and b) that the world would be a massively, massively better place if a) were to eventuate.
Your job is to buy as much Bitcoin as you can as cheaply as possible, cross your fingers and try and do whatever you can to make a) happen, while spending at little of your BTC as possible. You hope to profit immensely but you are also excited for how the world as a whole will profit.
If a) doesn't happen, then you basically have to go back to the drawing board for imagining a way for society to progress and you to make some money.

"believe"? You sound like a cult member. There is 0% chance that the world currencies will disappear anytime soon. If it did, bitcoins would be worth nothing anyways.

I think you are describing bitcoins...
The pathetic desperation of bitcoin fanatics like you is laughable. It's like listening to a retarded islamist.
