If you want to speculate, why do it with your own money?
I mine the most profitable coin and I speculate with my profits from mining. If I wanted to mine a less profitable coin, I would be wasting electric/profit/time to get x amount of coins, whereas mining the most profitable coin, my electric is paid, I don't have to spend all my profits on speculating and it takes me less time to acquire the less profitable coins.
Example: You mine coins that are valued at $30 per day, I mine coins valued at $50 a day. We both use the same amount and pay the same amount for electricity @ $10 a day. Out of my $40 profits I spend $20 on the coins you've mined.
$20 is a lot when you don't have it.

This is absolutely correct. I don't understand why so many miners struggle with this concept. The only exception to this rule is if the coin you wish to speculate on is not listed on any exchanges.
