I think no, we would see higher numbers of Crypto and altcoins in the future.
think of it, there are too many businesses around the world, some of them are local business while some of them are international as well.
investors are limited because the one who invest on businesses are only businessmen but today, there are so many cryptos or businesses that we could place our investments even we are not businessmen.
business in the world are growing and so as crypto market and there would be more altcoins available to invest in the future.
