my investment
This is one of the big problems I see. Lots of people think Bitcoin is some kind of "investment scheme", it's not. Would you "invest" your money by depositing it into PayPal? Bitcoin is a replacement for PayPal. Use it just like you would PayPal. If you need to accept or send a payment to/from someone over the internet, then use bitcoin. Buying bitcoins to speculate on the value is gambling, not investing.
ps. I'm not blind, I was just speaking generally as I continually hear people refer to their bitcoin "investment".
I think I have to disagree there.
Sure, bitcoin in itself shouldn't be used to "invest" but it is an inevital consequence of the fact that SOMEONE needs to hold all BTC at all time. This is different to FIAT that supply can be manipulated by an authority. So bitcoin can't only be used for currency by design.
That leads to a big advantage. As apposed to FIAT, Bitcoin is an excellent Store of value. While fiat will have a very high COMPOUNDED inflation rate, bitcoins inflation rate is predetermined and nocompounding, but rather decreasing till infinetisemal small inflation.
In conclusion: Someone must see Bitcoin as investment, otherwise the whole technologie wouldn't be able to serve its purpose as store of value and currency.
