An Ethereum ICO address that has been dormant for nearly 10 years was activated today. This address has remained inactive since the Ethereum initial coin offering in 2015 and currently holds 2,000 ETH, worth approximately $5.06 million. The cost of participating in the ICO at that time was only about $620. After activation, the address transferred 0.001 ETH in two separate transactions, with the specific use still unclear.
