The employee followed directions and sent an initial payment of $400 of Bitcoin to the above address. The net transfer was approximately .0055 BTC valued at $367 USD. This transaction occurred on 2024-04-23 23:44:55.

The employee then became skeptical and decided to not engage in any additional transfers, but he did not report his concerns to his shift manager.
