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?
no, what is only needed in crytocurrency is bitcoin and altcoin, the rest is just as crypto enthusiasts. actually without other coins crypto can run and will still exist. only ethereum and bitcoin can run crypto.
