"Positive ROI right now" - please explain more. You got your money back already?
if you payed something $250 and sell it next day for $750 that is what called "Positive ROI right now" and hell of a earning!!!!
you don't need to be genius to calculate that with 8GH power he didn't ROI in one month back! he is far away from that!
Exactly, I have been doing well by purchasing overpriced hardware mining for a bit with it and selling it on ebay for what I payed fro it or more, keeping the btc that was mined as well. I will admit some of it is timing and the other part is luck. The whole thing has been fun so far.
OK, so you are basically a hardware reseller not miner. Fine. Those "ebay idiots" will run out soon, hope you aren't left holding any underpowered mining hardware when that happens
Well no, I do a little of both, very low volume though. I sale hardware about once a month. I have been able to sell most all of it for more or equal to what it cost me, keeping the btc they mined. I have had some luck with timing selling at near highs and buying on the lows. To me it is a bit of a game and I realize that I can end up holding the bag as they say. Truth be told I probable would have made more money just buying and selling btc and not mining a bit of it, but what would be the fun on that.
Yeah, like you say, you risk "holding the bag" - your profits need to justify that risk. In the end, personally speaking, I am more interested in building up a nice BTC collection, but that's just me
