#PI Looking at the old four coins now, it reminds me of the early days of ETH. After Vitalik Buterin's presentation at Consensus 2015, Ethereum (ETH) has not yet been traded on exchanges. ETH was officially launched on July 30, 2015, and its first recorded transaction took place on August 7, 2015, at a price of about $2.83 per ETH. In the months following its launch, the price of ETH plummeted, reaching a low of around $0.45 in October 2015. By the end of 2015, it had rebounded to about $0.93, up about 32% from its opening price. Since the beginning of 2016, the price of Ethereum has risen steadily, reaching $10.03 on March 4, 2016. By mid-June 2016, it had soared above $18! In 2017, it reached a maximum of 10,000 yuan, an increase of 5,000 times in three years!
