It's not about the price of the tokens. I would like to emphasize that high valued tokens/coins DOES NOT REPRESENT THEY ARE GOOD TECHNOLOGY. Look at the price of their tokens/coins in the market, but they keep failing for the past 2 years and some are just starting up and failed right away before and after their launch with 2 MAJOR PROTOCOL BUGS. I am talking about EOS here, very disappointing.
Somehow you have a point. You also need to consider the maximum supply to determine if the price is high or low. On the other hand the value of the coin determine whether it is a good to invest or not but we have to consider that the coin should sustain it's value for a long time and not just a pump and dump scenario.
