Your OP falls into that insubstantial void of the reality of life for some people who limit their opportunities based on the chance for bitcoin to make them millionaires. Bitcoin is not different in investment value to any other existing asset in the fiat world, the great difference with any other asset that exists is that in itself it has the power to change a retrograde economic structure with a very important social asset and that can occur with any value that you put in Fiat currency.

Whatever!!
There are a variety of investments with which you could get money and start to forge your future, in practice when you have a family your goal is ... what I do to obtain benefits and offer a comfortable future that allows me to be happy. Bitcoin should be a part of that goal and not the whole.

bitcoin can become such a frequent means of payment that you may ask up paying you for your job in bitcoin, but there is also the possibility which currently for some becomes a mountain of money, but think that there is a unit called satoshi, so if maybe you manage to collect a million satoshi, that could ensure your future. Maybe!!
