Fallout 76

I have only completed the Raider faction entry to this quest but here is my advice on this topic for any Raiders out there:

PLEASE NOTE THAT THESE ARE MINOR SPOILERS


There are several ways in which you can get this achievement with relative ease. The easiest of which is simply to kill Johnny after getting to the point that he betrays you and either hand over 50% of the newly acquired gold bullion to Meg or keep all of it as this will guarantee that the player either receives 500 or 1000 gold bullion after quest completion. If you are determined to take the "Paragon of the Wastes" approach and give up your share to keep Johnny alive or allow the Secret Service to keep their gold then you can also do public events (please note that at the time of writing, the only public events that count towards getting gold bullion bills are the events marked with exclamation marks such as Heart of the Swamp and the Scorchbeast Queen events).

You can get both the Gold Rush and The New Fort Knox achievements easily.

Once you get a few treasury notes, you can go to the gold press machine and sell and repurchase your notes. Do not exit the machine, if you do, you will have to pick up more treasury notes.
