I follow them pretty heavily.  Bitinfocharts.com is a good place to collect data for many of the large blockchains.  Daily transactions, active addresses, sum value of transactions are good data points to look at. If those are increasingly monthly it will not be long before the token value increases.  Back in January the prices were getting way ahead of the usage but now these past few months have been the other way around.  Usage on certain blockchains are increasing exponentially while prices are flat to down.  Usage = demand, Supply and demand = price, so it will not be long now until we see a sustained bull run.
