First you say that you are the type of person who would want Bitcoins to stay the same and then that investing in them isn't a bad idea.
Who wants an investment to stay the same?

Make up your mind.
Either your are the visionary who wants a new, free currecy and service or you are the person who sees bitcoins as an investment.
You're not adding liquidity to the market, you are witholding it. As if you were to put your money under your madrass, except that would be stupid in addition to bad for the economy.

Corporations and nations have gold as a reserve currency and they spread the risk around with other currencies.
They want the opposite of any change; stability.
If anything they want their home/base currency to rise compared to others.

So in most  cases for example Switzerland would want the Suisse Franc to rise in comparison to the USD, Euro and even gold.
But they have the USD, Euro  and gold in reserve in case of their currency starts to fall.


Although this isn't completely true neither.
In fact on a macro-economic scale large corporations and nations sometimes want inflation.
For example (to my great dismay) Switzerland dumped its currency a few years ago because it was getting to strong.
I'm sure it was performing near gold levels.

And yes, we all try to boost our economic situation a little bit but I spread currency mostly for liquidity and security not for investment.
