And then there's the Bitcoin scam.

Get your Bitcoin.   There are only 21,000,000 of them (or something like that) in a planet of 7 Billion+ plus people.   The current price is around CAD3100 and has only gained about CAD1000 in the past ten days or so.  Just be aware that if you buy one, you are almost certainly supporting organized crime.

The price chart tells an interesting story.   Asymptotic increases are not a good thing.
