>Solis bought a Bitmain Antminer S9 on eBay for $2,400.
>As of this weekend, Solis has mined 1.01 BTC, worth a little more than $2,584 in his bitcoin wallet.

>"When I bought the miner, the price per bitcoin was around $1,200. I thought I’d break even in one year, but actually it’s been about five months."<p>So he would have been much better off just spending that 1,200 on Bitcoin rather than on a mining rig.
