A Bitcoin whale from 2013 sent test transactions of 0.0005 BTC ($43) from two wallets. Transfers of the same amount were made from each address. These wallets currently hold 1346 BTC (about $115 million).

The coins at these addresses were acquired 13 years ago for approximately $240,000, resulting in an estimated return of about 479x. The transactions can be seen on the address pages 1FZAt7NvBfVSxK1CSZYPENSdqoAB2y9gC5 and 19bFYeY3yEqctMWTLAFQHgEtq6KuDveew7. These are two small test transfers, initiated from each of the two addresses. Each transaction was for 0.0005 BTC, or about $43 per transfer. The total of 1346 BTC refers to the combined holdings of the two wallets.
