I think that these kinds of discussions of market cap and which assets are comparable in terms of utility are good, whether we be talking about theory or throwing numbers around - because in the end, we cannot know for sure how it is going to play out, but throwing out the theories and numbers can help us to view possible areas and to conceptualize what is more possible or not... and as we go along, we will continue to have to tweak our view of bitcoin and it's future based on developments in the space, whether those developments expand or contract bitcoin's actual market share, usage and utility.    $25k to $250k seems like reasonable possibilities in the coming 5-10 years - even if there may be some forces that continue to attempt to manipulate bitcoin down and to break it, possibilities of $25k to $250k seem reasonable(though certainly not inevitable - and that is where we have to account for the various forces that fight bitcoin in various ways that continue to make efforts to keep bitcoin down, and the downward force could also be explained by some attempts at downward speculation, even though downward speculation is not a complete explanation of downward price pressures, either).
