What you are saying is like bitcoin is unreliable, bitcoin is on the same level as altcoins, and bitcoin is afraid of altcoins taking its place. Bitcoin is king, which means no matter how many altcoins are created, they will never be able to compare with bitcoin. Even if we have millions more altcoins but as long as bitcoin outperforms all, there is no reason to fear. Every environment has competition, and if we are really strong, then there is no need to fear those who are weaker than us.
I dont think thats the message the OP is trying to pass. Bitcoin isnt on the same level as any alt coin and no alt coin has the capacity or potential to replace bitcoin.
The OP was talking about the possibility of having so many alt coins making it difficult and confusing for mostly newbies to make a decision on which coin to invest in. Bitcoin is bigger and better than all the other alt coins put together and cant be comparable in any way. Presently, there isnt any alt coin that is a threat to the dominance of bitcoin in the cryptocurrency space and I dont see anyone coming close to bitcoin anytime soon.
