may be it's better to just mine eth ? maybe it's not most profitable coin but at least it won't disappear like those altcoins and it has huge volume on exchanges and good potential to grow? 
You can mine ETH easily. It gives you stable profit. On another hand - you can spend your time to search for higher profit with different shitcoins. Some of them are enough powerful but it continue to be a shitcoin. And in any moment your profit can become zero.
