I've been holding my altcoins for years now and waiting for bullrun to make a better come back but I'm yet to be confused that this is the real bullrun since many altcoins don't bother favouring from the bullrun,what is going on?

Never rely on just bull run because this will only leads you to frustration and failure,this market is volatile and being manipulated by some(well I have no proof but it has been the issue for long time now)so I think looking for bull is harder to become reality
Why not just wait for slow growth but rightfully?i mean the normal growth of each coins that depend on the true investors and not from those who wants shits to pump and to dump the good moving coins
