I imagine if there is a lot of altcoins, there will be altcoins that will not survive and eventually lost. Will altcoins that survive has the capacity to raise its value as high as bitcoin?
There is no problem if there is a lot of altcoins that exist. And there will be no problem if a lot of them are not good. We only have to focus on coins that have a good project development behind it and invest in it. And yes, there is a possibility that some altcoins may reach bitcoin's price or even surpass bitcoin's price.
