Next Big Coin?

So we all know the people who really made the money in Eth were the one's mining the coin prior to this year. The difficulty has increased by over 400% since. People who were mining Eth all last year were raking in the cash and anyone who held onto it is fairly well off.

That being said I wanted to start a discussion on the next new coin. What coin do you all think will be next to blow? Has anyone considered mining a less popular coin in hopes that it blows up in value? If you mine a coin that has a much lower difficulty.
