Altcoins is a short cut term for alternative coins. This is base on my understanding as to what I have read and learn it from others. Due to the numbers of existing altcoins in the market I bet that there could be an altcoin who made one to change his life by earning huge profit.
Altcoins is a life changer for me as i have the opportunity to earn more profit through them though not all the time because i do suffer loses sometimes. Though some of us here considered altcoins as shit coins but we can't eliminate the fact that it is that coins that provide wealth to most of us here in the community.
