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?
Yes, because lots of them are offering alternative technical features that bitcoin does not have. They also have different transaction commission costs and speeds that certain users can't afford for BTC. There are many other reasons, but the basic one is the increase of variety in the market. Imagine there was only one e-mail service provider on the net...
Good luck!
Exactly, I totally agree. You can think of it like an enormous market with various industries. And let's say every single industry requires at least one altcoin (there are many companies which compete in one industry). So it is not a surprise that there are lots of altcoins and they are necessary!
