First of all, it is impossible to directly modify gems, duel orbs, gold or whatever account stats. That's because accounts are server-sided. The only way we can get those items faster is by cheating and botting. There are many scammers advertising these fake hacks. Don't fall for them.
Hence, in the following I will show you how to do that.
In general, leveling up characters will give you the highest gem income. When you do this, make sure to prioritize "older" characters which still have a 300 gem reward for reaching level 30. Most duel monsters and GX characters will have them. You should therefore not level up any of the 5D's characters, unless you really want their reward cards.
For the actual gem farming:
Dueling at the gate against level 10 legendary duelists with a multiplier of x3 is the fastest way to level up. If you enable one of the duel skippers you run a higher risk of getting warned/banned but they will let you farm even faster. A safe way to do this would be to auto duel the gate with the auto duel mod enabled. For this you can either run the gate farming bot or play manually. If you run out of keys, stick to the casual duels farming with the bot. Running the casual duels farming bot over night is also a great way to level up characters and to earn keys/gold etc. easily.
Of course you should still play some ranked duels or events since they always drop some extra gems.
About farming skills:
Run the casual duels farming bot overnight. You will earn most, if not all skills in 1 - 2 nights/days of farming.
Thanks for reading, enjoy.
