In 2017, Lao Ma in Shanghai heard that buying Bitcoin could make a lot of money, so he asked around. Finally, under the introduction of a friend, he bought a large amount of BTC worth about 3 million yuan at a price of 10,000 US dollars. The friend issued him a voucher and sent him a set of steel coins two days later.

Lao Ma didn't understand. This thing is worth 5 million? The friend told him that it was a collectible, and Lao Ma understood it instantly.

In 2021, the overwhelming bull market news came out, and BTC rose to 60,000 US dollars. Lao Ma was very excited and happy. He immediately contacted people to sell BTC, and then the seller was stunned when he heard what he said. This idiot bought a steel coin.

Later, Lao Ma could not contact that friend, and he didn't know whether that friend bought the real BTC.
