in memory of my first usb bitcoin miner.
this tiny USB device has 300M Hash power.
It used to dig 0.001 BTC per day, 4 years ago.
each USB device sold at approximately $100 back then.
I won't use it anymore. just keep it as a souvenir of my sweet mining moments.
Oh, my precious coin!
人生中第一台比特币矿机，算力只有300M，当时可以每天给我挖0.001比特币。
现在是我的收藏品，不再使用它了。很有纪念意义。
