Do you still need new coins from the current Altcoin? basically everything is the same, namely to transact between two or more individuals, by using the internet to speed up transactions and also reduce transaction costs.
No need for many coins to be born, all we need is how cryptocurrency can begin to be used to make payments easier and safer
The problem with that is, if I was to pay for something with a altcoin, I would want to be damn sure that it will not be worth a 1000% more next week. So we need a low or stable value coin.
