How much (%) of your mining income (or profit) goes back into expanding/replacing mining capacity? I know mining is for people with money but I wonder what's the smallest investment that can actually be self-sustaining in mining?

Myself I have free hosting (paid in bulk by another business of mine). but even so, the total returns on my mining are not enough to get something more than an S7 after several months, an S9 at the moment would mean putting some of my own money into this..again. So I wonder how much I should set aside (10, 50%, 100%?) to replace old hardware like S4,S5.

Free hosting? I would suggest, and this is just me and what I do, without free hosting, is take the money I get from mining, move it to an exchange and trade in alt coins to make more Bitcoin, which I am getting really good at, and then use the coin to purchase another S9 when I can, rinse and repeat.

If you have free hosting then you have no electric to cover like I do so you should be able to get going in no time at all as at the current Bitcoin exchange rate an S9 costs about .41 Bitcoin.

If you actually have "free" hosting, there's no reason for you to not make money in the present market. I have a couple of 741s on free power here at home; there are 3 S7s in Labrador that I pay hosting on; and I'm sitting on a pile of S3s, an S2, and there's a 721 and another 741 looking for a power outlet.

To answer your basic question, though...I don't "set aside" anything, because I do not use my BTC income for general expenses; I save all my BTC for future needs. I may tap into it for an emergency expense, but that's it. If I need a "new" machine, there is generally enough there to buy it if I need to. Bottom line? 100% I guess.

I'm one of the "we don't need no stinking alt coins" folks, I'm afraid. I have no interest in that sort of trading, but I don't fault those who choose to. It's your fiat...so to speak... Kiss

Mine on...

@ firetreeactual - I'm like you and run 2 741's at home now and looking to try running 3rd soon and shipping few to Labrador soon. Wink

I wanted to know how you handle several 741's running at home (ie. sound / heat). I had friends with free electricity that wanted to host some of them but in this summer heat miners are too much for apartments and they bailed out.
