You raid constantly. Manage your trophies for easy loot and look for abandoned villages with well developed mines. Searchp 'farming' on the wiki - there are some good guides
Try dropping your trophies a little bit, so u are attacking smaller people. Use giants and goblins. Giants break into the walls, and goblins clear out all of the defenses.
Drop your Trophies, find a good Division to Farm, leave your Town Hall Outside, Must have a really nice Army Composition for Raiding, 1 vacant builder for upgrading your walls when you are online and farming.. enjoy while you are playing.. :)
i agree with this but will also add, boost your barracks! You get WAY more raids in, especially if you are barching. As for gold, I do my best (as a th8) in the 1600-1700 range.
Note: when i boost i average 3.5-4 million in gold every two hours in gold 2. I barch.
I like to use B.A.G for my simple raid. Use it so you save your elixir
Just DON'T DO:
1.upgrade in lab
2.too long offline
3.put TH inside
