Why the 10% discount matters more than it sounds
FOMO Social charges a performance-based trading fee on each copy trade. At 0.50%, a trader placing 200 trades per month on a $2,000 account pays real money in fees. With JOIN100 that drops to 0.45% — and because the saving compounds across every single order, active copy traders recover the discount hundreds of times over in a year.
What the fee saving looks like per month
| Monthly trade volume | Fee at 0.50% | Fee at 0.45% with JOIN100 | You save | |
|---|---|---|---|---|
| $5,000 | $25.00 | $22.50 | $2.50 | |
| $10,000 | $50.00 | $45.00 | $5.00 | |
| $25,000 | $125.00 | $112.50 | $12.50 | |
| $50,000 | $250.00 | $225.00 | $25.00 | |
| $100,000 | $500.00 | $450.00 | $50.00 |

How to apply the JOIN100 code, step by step
- Open the FOMO sign-up page — the referral code JOIN100 is pre-filled when you use this link.
- Create your account with email or your preferred wallet login.
- Check that the referral field shows JOIN100 before you confirm.
- Deposit funds and pick the traders you want to copy.
- From your first trade onward, every fee is charged at 0.45% instead of 0.50%.
If you sign up without the link, you can still type JOIN100 manually into the referral field during registration — but the code cannot be added after the account exists, so double-check before you finish signup.
Field notes from actually using the discount
A few practical observations that rarely make it into the marketing copy:
- The discount applies per trade, not per day. A day with 30 copied orders saves 30 times 0.05% — not once.
- It stacks with choosing low-fee copy strategies. Traders who copy fewer, larger positions pay less in total fees than those copying many small ones. Combine JOIN100 with deliberate position sizing.
- Slippage is separate. The 10% discount reduces FOMO's fee, not network or slippage costs on-chain.
- The code is one-time at signup. There is no way to retro-apply it, which is why the referral field deserves a second look before you hit confirm.

Common mistakes when entering the code
- Typing join100 in lowercase — the field usually accepts it, but JOIN100 in capitals is the safest form.
- Leaving the referral field blank because it looks optional. Blank means full 0.50% fees forever.
- Signing up through the app store link instead of a referral link — the app-store flow sometimes skips the referral step entirely.
- Waiting to "use it later". JOIN100 only works during signup; there is no second chance.
Who should use the JOIN100 code
Anyone opening a FOMO account, honestly. Casual traders copying a handful of positions still save on every order, and high-frequency copy traders save thousands per year at scale. Since the code costs nothing, takes two seconds to enter and cannot be added afterwards, the only wrong move is skipping it.
