I don't sell anything, I mine and hold. And hold. And hold. I'm waiting for a massive gain or nothing at all. It's pointless to me to mine and sell immediately for like what, $20/day profit and dropping every couple weeks?
Why don't you just buy bitcoins on exchange and hold it? It's cheaper.
Because I don't mine bitcoin. I got into mining altcoins. Some I have traded for bitcoin but I wouldn't say my majority holdings are btc - not by a long shot. Having mining equipment lets me speculate on many different coins. Naturally when I bought the equipment I was (and still am) gambling on making enough profit simply by mining, to profit over the cost of the equipment, in addition to any profit from price increases.
