Is not cheap neither is free (.1 Kw/h) but anyway the way that i see it eventually i gonna brake even also got dash and more L3 miners on the way + this is a learning experience thats gonna give me the knowledge that i need to do a bigger project in the near future. Knowledge is not free at least not this kind i think.
Ten cents per KwH? I'd have considered Altcoin mining at that power rate earlier in the year, but Bitcoin is more stable as we've all noticed. Not a bad electrical cost, most people have costs much above that. Knowledge is mostly just electrical work in Bitcoin and a little bit of dirty work, if you plan on getting some kind of large building or factory for mining you'll learn even more

You can actually learn a lot about BTC mining without actually having a miner, but for the electrical work, it does help to know a bit and possibly shave some money off of that.
