Oh, I'll figure something out. What I like about the altcoins is that they're easier. The same calculator shows I'm breaking even with the old Gridseed G-Blade I've got. And 100 watts I can sneak by on free power, not 1 KW or more. https://www.cryptocompare.com/mining/calculator/ltc?HashingPower=4.75&HashingUnit=MH%2Fs&PowerConsumption=100&CostPerkWh=0.12
That's the good thing about altcoins and the difference is that many altcoins use scrypt or algorithms similar that can have miners that adapt to them. If you buy a bitcoin miner it only does SHA256, but there are quite a few miners specifically designed to change depending on the algorithm (scrypt/x11...) So you can switch altcoins to mine easily if that one becomes unprofitable.
If you are doing it as a hobby, then your S3+ will be good for showinig you what to do. If you're doing it for profit and in a place with energy that isn't very cheap (and I think $0.12/KWh is considered on the upper end of energy fees), but you could look at a site for cloudmining such as hashnest.com (this is probably the only one that has chance of returning you your roi - but it won't be as interesting as mining for yourself, the others are mainly scams)
