What is the easiest way to farm bright dust?

[Goblin]

I been looking as the additional bounties give 10 bright dust each but which extra bounties should i be taking or is there another method i should focus on?

Unless you actually need bright dust in a hurry and are willing to put hours into grinding the repeatables I'd say just stick to the seasonal challenges to get the big payout at the end of the season for completing most challenges as well as the experience filling up the seasonal ranks for bright dust. IIRC unless they changed it the complete 8 bounties for vanguard, gambit, and crucible should still give some bright dust and can be completed each week on all 3 characters.

3. make cookies using repeatable event bounties

5. congratulations on your 20k bright dust

Seasonal challenges are a good source.
The tower vendor bounties give a good bright dust boost after each weekly reset when you turn in 8 of them and claim your reward for it.

(And, if you are lucky, sometimes an Eververse Engram might give you some bright dust, but that's hardly worth to chase after since that's completely RNG. :-)
