Coinbase director Conor Grogan wrote that he found about 430 BTC in dozens of wallets associated with Silk Road founder Ross Ulbricht. These wallets have not been confiscated by the US government and have not been touched for more than 13 years. At that time, these wallets may have been "dust wallets (referring to the insignificant amount in the wallet) ". Now they are worth about $47 million in total. If Ross Ulbricht can still find the private key, this part of the asset may be recovered.
