Competition between the Altcoins has been and always will be. This is a normal healthy process that will always encourage cryptocurrency to improve and compete. Therefore, if Bitcoin remains in such a pathetic for a long time, we see it with seven transactions per second, according to the laws of the market, it will be shifted from leadership to cryptocurrency.
I think that over time the number of types of cryptocurrency will increase, and mainly due to an increase in the number of tokens. We need tokens because they are used in a narrow area of human activity and make it much easier, making it more comfortable and safer.
