I believe that bitcoin is a terrible investment at this time.
May I ask, what is a good investment you would recommend at this time? The very meaning of the word involves risk and you're right about it from one point of view and it is that people shouldn't be investing sums that they couldn't do without the next week. Now, this isn't an investment, this is pure stupidity. But then again this isn't a general investment advice club either.
I'm sure there are many low risk low reward ops, including your local bank's "superb-interest" accounts. They'll make a ton of profits on it and pay you a tiny percent of what they make. Virtually risk free and small gain investment. If you include inflation in the math, you'll realize you actually lost money at the end of the year, but there you go.
