what you call "bull run" in altcoin market has always been the same, every single altcoin gets pumped with a couple of exceptions. the last pumping season was the season of ICOs and consequently the platform tokens such as ether that people were forced to buy got the biggest pumps.

next time will not be any different either. every single altcoin will get pumped with exception of certain groups (which we don't know which one yet now) will get bigger pumps. last time it was platform tokens but next one it will be something new.

maybe privacy coins this time?
