I would wait for Bitcoin to crash to about $400 or whatever it bottoms out at in the next few months. First, because it’s going to crash. It will be many, many years before Bitcoin is any sort of stable. Second, the bottom seems to be pretty stable for a while before it starts climbing significantly again.

Then I would invest $990 all on Bitcoin and spend the rest on tacos to celebrate, while calculating the true cost of those tacos when Bitcoin reaches $3000, $40,000, and $500,000. I think that it really will reach that last value in the next 30 or so years.
