Altcoins today are struggling , yes no doubt about that but if much attentions are giving to some altcoins with lots of potentials, i think it will make altcoins standout in the market. although some altcoins lacks vision and there are several coins i believe will defintely change the market positively.
Unfortunately, this has already been going on for a year and a half and there is nothing to be done about it, because we cant name the reason why manipulators and big players pump only Bitcoin, and they dont touch altcoins at all, so the only thing we can do is sit and wait when altcoins season will start, but at the moment, of course, we need to expand our portfolio with as many different altcoins as possible, because bitcoin will not grow forever and altcoins will not fall forever.
