When I look at this, it makes me rethink on getting actual physical hardware and just go win something for cheap on ebay and exchange it to sell here on the forum.
And then get 1 sold bitcoin, instead of getting a massive electric bill and energy to maintain all of these things.
Its cool to look at though, but just doesnt make much sense to me esp when I know the coin can go down at any time of the day.
You forgot the hope that the coin can go up anyday. Many miners are in BTC for the long term, as this is still considered the early phase for BTC.
