Is this guy for real? You seriously compared BTC farming where you are guaranteed to earn 20%+/- less every 10 days? And if the difficultly increase is gonna average out to 25% (which is more than plausible) you'll never see ROI.
I like it how you causally type that you'll make 14$ a day as if it's a constant.
If you wanna unplug your rig and sell it, than by all means, but from there to buying an antminer as if it's something profitable and so much better... lol.
Dude probably wasn't using a calculator with a difficulty chart. Difficulty for Bitcoin mining has been pretty steady: Just up up and up.
For example, Bitmain just released their 1TH machines (1000w usage, comes with the PSU). After meeting ROI on them, you'll MAYBE make ~$1,000 on them, after having spent ~$4000 for the miner itself. $1,000 isn't small money, but if you want mining to become a day-job, you either need to have the dough to invest a ton up front, or know how to make your own chips.
