I actually... kind of like it. Right now there are good opportunities to mine pumped crap and convert into BTC/LTC. If I pick the right coin, I can mine 2-3X worth of LTC than I'd otherwise mine doing straight LTC.
Dont BS, I do the same, most you can do is 1.5x LTC direct mining, thats only if you sell right away. With the way altcoins are dropping fast I wouldve had a lot more if I had directly mined LTC. All my stupid DOGE Im holding on to are worth 1/3 of when I mined them. Garbage after garbage come out. I cant believe with all these altcoins anyone is still buying bitcoin itself.
I haven't done this, but I did mine LTC, convert to BTC, speculate on NXT and gain about 7x the value I mined
