Now you only need 357 Bitcoin to be a millionaire. That is really my dream but I doubt it will ever happen. I guess the saying is correct, the rich get richer and the poor don't. Modified saying.

With respect to bitcoin's opportunities, I might want to differ with that saying. When a poor would have decided to buy some bitcoins for at least $10 some five or six years back, you would have turned a millionaire by this time.
We cannot say poor does not have $10. Only knowledge and perception on future really matter here. People got chances to enter into bitcoins in early days and got chances to come millionaire only if they have decided to save it till today. Not all the rich is becoming richer, but only those who are capable of foreseeing the future.
