That 50 yuan Bitcoin died in 2011. Fifteen years ago, if you searched for "Bitcoin" on Taobao, you could find many treasures priced at 50 yuan. The seller will tirelessly teach you how to download that ugly client on Wangwang, just to transfer the "digital toy" you took a picture of to you. In that era, this 50 yuan was not an investment, but a "cyber consumption" with a curious mentality. In the eyes of most people, it is no different from Q coins and game cards, and even less practical. That was a crazy and primitive era: At the beginning of 2011, the price was still hovering around 0.3 US dollars (about 2 yuan), and 50 yuan could buy a bunch. May 2011: the first foam, which soared to $30 (about 190 yuan). The second half of 2011: the foam burst and the price halved. So, when someone spent 50 yuan to buy a Bitcoin at that time, the transaction even seemed a bit "expensive" and "foolish" at the time. That is a corner that only geeks, punks, and gamblers care about. Fifteen years, the sea has changed. Today, when we mention the "50 RMB Bitcoin" again, it is no longer an achievable transaction, but a life level missed opportunity sealed by time. The "digital toy" worth 50 yuan, which was once readily available on Taobao, died in 2011. It won't come back again. Just like yesterday when SEC Chairman Paul Atkins announced the "complete end of the regulatory gray zone," Bitcoin has also bid farewell to its cheap and wild past. It is no longer the neglected non security, it is the most expensive consensus of this era, and also a historical coordinate that can never be returned.
