We're all mostly like minded people here. But if you ask your neighbors or family or friends if they consider Bitcoin a "safe investment" most will probably say "No!"

We have a long way to go to get to that point. There's really nothing safe about Bitcoin yet. It's initial purpose was to be a currency and there's not a lot of growth in accepting it (from Retailers) as a currency. The prices swing wildly. This fork isn't over...SegWit2x won't be clear until November. And there's hundreds of copycat alternative coins that muttle the perception of Bitcoin.

Would I invest in Bitcoin for retirement purposes? Yes. I do.

Would I expect the people in my circle that barely know what Bitcoin is to think the same way? Absolutely not.

We should start by trying to educate people on what Bitcoin is and why we believe it has value. People will say...oh, it doesn't have intrinsic value...well neither does fiat currency or gold. All three only have value because a group of people agree to assign value to it. Once you get people to understand this you can start to discuss how the lack of a central authority minimizes the opportunity for manipulation and that it's finite money supply will help combat (if not eliminate) deflation of value in the future, etc.

We need to start with the basics and always in comparative terms to fiat and gold...mediums of exchange that we want Bitcoin to be compared to.
