You have to find the method that works right for you, but they're all pretty grindy. Run dungeons and sell all the A-gear you can get your hands on. Run regionals and sell of all of the enhancement pieces you get. Farm ancient chests to sell recipes. Join the Artisan's Union, cook yourself some gathering speed food, pop a gathering speed scroll and put on a set of gathering speed gear, then farm northern sperios for gold from your mount. I personally don't run dungeons very much, so I sell any spare keys. If you hoard keys until right after a double chest event, you can sell them for more. Pretty much everything u/StudMuffinNick said
