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?
Definitely other altcoins are needed to further pump crypto as a whole. As you can see, Altcoins are necessary coins for investor to provide exclusive services to consumers. In that sense, They will be more encouraged to invest to cryptocurrency which adds to the flow of values in this platform. Since most of the tokens are derived from BTc or ETH as a platform, they get affected by the rise and fall of the platform to which they are derived.
This rule created by the cryptocurrency traders in the market.
Nothing created this rule, only by the trader feel this rule is true for the cryptocurrency, it became the truth and the right choice for anyone want to invest.
Finally, these things created by the whale and use that rule to take advantage the mentality of the trader.
