Not everyone will be able to profit off of bitcoin. Worse, those who will, will do so at the expense of everyone else.

There's only two ways this bubble will burst:

1. Inflation: the value of fiat currencies drops to match the supposed value of bitcoin, which negatively affects everyone

2. Only the first people to cash out actually turn a profit. Every other person who invested will lose everything.

Either way, the money you now made from bitcoin, came from people who will probably lose their savings contributing to the bubble.
