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 we do. Altcoin is an alternative cryptocurrency (to Bitcoin), and each alt offers its possibilities. Many altcoins are safer than BTC and their transactions are faster. They are more anonymous and you can use these coins for different purposes: for ICOs, buying/selling stuff in internet, even paying in restaurant!
