当然是买来的！现在比特币越来越难挖了，挖矿比的是计算机的性能，投资几万块买挖矿机说不定几年都收不回成本。我就是小玩一把，收藏几个。现在不是股市楼市黄金都不景气了吗，关注下比特币。

Of course I bought them. Nowadays Bitcoins are becoming more and more difficult to mine. Mining for Bitcoins is a task for computers. If you invest tens of thousands of kuai to buy a machine to mine Bitcoins, you won't necessarily get a return on your investment for years. I'm just playing around with it a bit and collecting a few. Nowadays aren't the stock market, real estate and gold all in decline? The focus is on Bitcoin.
