Can some people please give me a quick rundown on what these Altcoins are in relation to Bitcoin ?

Are they like Alternative versions of Bitcoin with different Features or Specifications ?

Will they be around for as long as Bitcoin or do they get created & then abandoned ?

Hello Crypto World,

I have just signed up to this interesting forum, there looks like a lot of stuff I have to sift through but I'm glad there is a search feature to help me out

Hopefully I will see you all around soon after doing some more research on CryptoCurrencies & "The Game"
