Crypto Currencies are all over the place these days. And they are popping up everywhere. It seems like everyone is coming out with their own coin. Many of these coins are worthless. However there is a place and benefit to them. If the shitcoins have a place on exchange sites then this means they can be traded for a better currency. Since such coins are technically are shit less people are mining them allowing for people with a just a CPU to easily mine them and get a little something.
In this case the miners with nothing have gained something and they can then exchange that nothing for something like BTC or BCH
