Every beginner needs to know that 99% of altcoins will go to zero. Perhaps a few of the altcoins we have right now will survive the long run. History has proven that altcoins usually do not have anything to offer and are mostly speculative instruments in the cryptocurrency world.
Bitcoin is the King. Remember this when the next forked coin claims it will do the flippening and replace Bitcoin in dominance. Don't make the mistake to listen to sock puppets and influencers.
