In the long run almost every potential cryptocurrency gains in price
it's really the opposite
for what I have seen and I can show you with some data taken during "ICO MANIA" of 2017. I get some data from this topic https://bitcointalk.org/index.php?topic=2106360.0 "The next 100x or 1000x coin", where people trying to guess/suggest the coin that could receive a big pump during end of 2017 early 2018.
Plus coins were suggested here as the best coins for a speculation ... and these are the results after 3 years:
13,18% Reported a positive result.
10.83% Reported a 0 (total loss)
the others just negative results (prices go down).

The term 'potential cryptocurrencies' is subjective here and can lead to coins with one's own perspective of how potential they are.
For me, bitcoin and ether (and recently DOT) are the most potential coins and they have crossed their ATH recently.
So yes, they did increase in price in the long run right. I know that many cryptocurrencies depreciate in price but I believe the potential ones just gain in the long run.
