Nice thoughts on numbers, I do consider circulation when choosing the coin. I do consider even more the total amount of the coins to be issued eventually, what should play a dramatic role very long term. Not to mention the advantage of limited emission. We also have to take into account coins emission speed, that may differ a lot. I see some comments from newbies here. Apart from numbers counting, smart investing suggests the understanding of the product you are about to invest in. So before you pick up seemingly undervalued coin, do your research on the coin, how promising the project looks, what's the idea, what are advantages and real use, how large is the coin community (forums), how active developers and marketing are, how many followers on social network and so on. In this case, you will be happy to hold the coin long term not dumping it when there are major downtrends sometimes. There are dead or potentially dead ICO's already with the inactive dev team. Just my 50 cents ))
