Isn't mining the more profitable coin safer? or do people just constantly mine the less profitable coin and try to trade the volatility of it hoping to catch a swing? I get spec mining when you are mining a brand new coin and difficulty is non existent and value of a coin is completely unknown, but we're talking Ella and Komodo here.
You got the right strategy in mind. Mining the most profitable coin is usually the simplest and the best because you can simply buy speculative coins with it anyway. The thing is some people go balls deep into speculation that they mine coins that aren't even listed on any exchanges yet. Those are the coins where people expect to gain significantly.
When you think of it, its almost like gambling already.
