Whatever the BTC price may be, considering pure ratio of supply limit on some coins compared to BTC, they should be at least a third or half that. One only needs to look at lite coin to know this is not the case. I am sure mining rates and other factors such as ease of trade and current number of coins available play a part.

Some one enlighten me on what it would take for these coins to inflate in relative value against BTC in the future. More public interest? More exchange acceptance?

Is it even possible? Are the current exchange ratios really undervalued, or are they stable the way they are?
