Re: what do u think will happen 100 years or 1000 years from now
I accept the first part of the conversation that the price will move higher with more investment coming into bitcoin and with time we will reach a point where the price will be stable and it will take a long time, but that does not mean that the price would be a million dollars per coin and the rest of the people who invested in something else will end up in a loosing position, i am not sure what theory you are talking about, with zero investment the end result is null and not negative 
.
It is actually possible for BTC to become a million dollars in future which has been predicted by great analyst for future, bitcoin was once $1, which is not 5000, which means we have 5000x on it, imagine another 500x on it within the next 30 years, and bitcoin reaching that value would have also move other coins too higher in value, which means those who still invested in other coins too have still not lost..It is possible for people who never paid attention to BTC now to regret even if they are engaged in other things that are fetching them money, but no matter what they invested in then, the profit can never be as much as what Bitcoin would give in some years time.
