No, you should not invest in Bitcoin. The reason is that it’s not an investment. Just like gold, tulip bulbs, Beanie Babies, 1999 dotcoms without any hope of a product plan, “pre-construction pricing” Toronto condominiums you have no intent to occupy or rent out, and rare baseball cards are not investments.
These are all things that people have bought in the past, and driven to completely irrational prices, not because they did anything useful or produced any money and value to society, but solely because they thought they would be able to sell them to someone else for more in the future.
When you make this kind of purchase, which you should never do, you are speculating, which is not a useful activity. You’re playing a psychological, win-lose battle against other humans with money as the only objective.
