What the JOIN100 code actually does
FOMO is a social copy trading app: you follow experienced traders, and their trades can be mirrored to your own account automatically. Like every trading platform, FOMO charges a fee on each executed trade — and those fees add up fast when you copy several traders at once.
The referral code JOIN100 cuts that fee by 10% for eligible new users. Nothing about your trading changes: same markets, same copy features, same withdrawal options. You simply keep a bigger share of every profitable trade.
Where to enter the referral code, step by step
On the mobile app
- Download the FOMO app from the App Store or Google Play.
- Tap Sign up and create your account with email or a connected wallet.
- Look for the field labelled Referral code (it may sit under "Have an invite code?").
- Type JOIN100 exactly — capital letters, no spaces.
- Confirm, finish registration, and make your first deposit.
On the website
- Open fomo.family/r/JOIN100 — the code is applied automatically when you register through this link.
- Complete the sign-up form.
- Check your account or profile settings to confirm the referral is attached before you trade.
> Tip: the discount applies from registration. If you already created an account without a code, contact FOMO support before your first trade — codes usually cannot be added retroactively after significant activity.
How much does 10% actually save you?
The savings scale with how much you copy-trade. Here is the math on realistic monthly volumes, assuming a 0.50% base trading fee:
| Monthly trade volume | Fee without JOIN100 | Fee with JOIN100 (10% off) | You keep | |
|---|---|---|---|---|
| $1,000 | $5.00 | $4.50 | $0.50 | |
| $5,000 | $25.00 | $22.50 | $2.50 | |
| $10,000 | $50.00 | $45.00 | $5.00 | |
| $50,000 | $250.00 | $225.00 | $25.00 |
Over a year, a $5,000-per-month trader saves $30 — and heavier traders save proportionally more. Run your own numbers in our free crypto copy trading fee calculator to see the difference across FOMO, Axiom, Runnr, Photon and GMGN side by side.
Why a referral code beats a "promo code"
People search for both terms, but they work differently:
| Referral code (JOIN100) | Generic promo code | ||
|---|---|---|---|
| Who it is for | New users registering through an invite | Anyone, often during campaigns | |
| Duration | Attached to your account at sign-up | Usually expires | |
| Stacking | Often cannot combine with other offers | Rarely stacks either | |
| Reliability | Verified working for 2026 | Frequently dead links |
Because JOIN100 is a referral code, it is tied to your account from day one — you do not need to re-enter anything later.
Common mistakes to avoid
- Typing the code after registering. The field only exists during sign-up.
- Lowercase or spacing errors. Enter it exactly as JOIN100.
- Using a copied link that stripped the code. Register through the official JOIN100 link to be safe.
- Assuming the discount covers network fees. The 10% applies to trading fees; blockchain network fees are separate.
- Waiting for a "better" code. There is no higher public discount — JOIN100 is the standard working code.

Frequently asked questions
Is the Fomo app referral code still working in 2026?
Yes. JOIN100 is active and gives eligible new users 10% off trading fees.
Can I add the code after I already signed up?
Usually no — the referral field only appears during registration. Contact FOMO support quickly if you just created your account; otherwise register through the JOIN100 link.
Does JOIN100 expire?
There is no published expiry date, but referral programs can change at any time. Use it with your first registration rather than saving it for later.
Does the discount apply to copied trades too?
Yes — every executed trade on your account is charged the reduced fee, including trades copied from broadcasters you follow.
Is copy trading on FOMO safe?
Copy trading always carries risk: you can lose money following a trader who underperforms. The referral code reduces your costs, not your risk. Never deposit more than you can afford to lose, and review a broadcaster's track record before following them.
