There are Bitcoin, and also there are Bitcoin Cash and Bitcoin Gold and B2X that we use it as an altcoin, but do we still need other altcoins? as i knew in the forum on the altcoin section there are much announcement about new altcoins almost everyday. do we still need that altcoins?
As far as I understand, most of the altcoins are used by the ICO and business in order to promote their project through the means of it as a token for the investors. It is a way to manage investors so that, those investors can sell the altcoins when the project has a very good market value.
