This is a very rough idea. If we repeat a similar alt season to early 2018 we could potentially use fib extensions on alts to predict ATH based on current BTC ATH since the alts trailed BTC's trend in the last major bull cycle. Current BTC is sitting around 60k, which if you look at the fibs is a little over 300% increase on the 2017 spike. If you apply the same principle to NEO and look at where the 300% mark is, you will see it is somewhere around the $700 mark. This may of course even be a low projection, since alts often have the tendency to multiply greater than btc.
