What the JOIN100 code actually gives you
FOMO charges a fee on every trade you copy or execute. With JOIN100 applied, eligible users pay 10% less on those fees. On an active copy trading account that compounds quickly: fewer fees on every copied trade means more of your capital stays in your positions instead of leaking away to costs.
Three things worth knowing:
- The discount applies per trade. Every eligible trade costs 10% less in fees, not just your first one.
- It never expires. Once JOIN100 is attached to your account, the reduced fee rate applies going forward.
- It costs you nothing extra. Referral codes are how FOMO rewards users who sign up through a shared link — you get a discount, and the person who shared the link gets a small referral credit from FOMO, not from your balance.
Where to enter the FOMO referral code
On mobile (most common)
- Open the signup link: fomo.family/r/JOIN100. Opening the link pre-fills the code for most users.
- Create your account with your email or preferred sign-in method.
- If the referral field appears empty, type JOIN100 manually.
- Confirm your account and make your first deposit.
- Start copy trading — the 10% fee reduction applies automatically from your first trade.
On the website
- Go to the FOMO registration page through the JOIN100 link.
- Look for a field labelled Referral code, Invite code, or Promo code — usually below the email field.
- Enter JOIN100 exactly, no spaces, no quotation marks.
- Finish registration and confirm your email.
If you already have an account
If you signed up without a code, the discount usually cannot be applied retroactively. In that case, contact FOMO support and mention JOIN100 — some teams apply it within a short window after signup. If that fails, the cleanest option is to register a fresh account through the JOIN100 link.
How much can you save with JOIN100?
The savings depend on your trading volume. Here is an illustrative calculation at a 0.50% base fee per trade, before the 10% discount:
| Monthly copied volume | Fee without code (0.50%) | Fee with JOIN100 | You save per month | You save per year | |
|---|---|---|---|---|---|
| $1,000 | $5.00 | $4.50 | $0.50 | $6.00 | |
| $5,000 | $25.00 | $22.50 | $2.50 | $30.00 | |
| $10,000 | $50.00 | $45.00 | $5.00 | $60.00 | |
| $25,000 | $125.00 | $112.50 | $12.50 | $150.00 | |
| $50,000 | $250.00 | $225.00 | $25.00 | $300.00 |

Referral code vs promo code: what is the difference?
People search for both terms, and on FOMO they effectively point to the same thing:
| Referral code (JOIN100) | Promo code | ||
|---|---|---|---|
| Who issues it | An existing user through their invite link | FOMO during marketing campaigns | |
| Availability | Always — shared links never expire | Temporary — campaign-dependent | |
| What you get | 10% fee discount for eligible users | Varies: bonuses, fee credits, discounts | |
| Where to enter it | Signup screen, referral field | Signup screen, promo field |
Because JOIN100 works year-round, you do not need to wait for a promotion to get a discount.
Common mistakes when entering the code
| Mistake | What happens | How to avoid it | |
|---|---|---|---|
| Typing the code after signup | Discount cannot be applied | Enter JOIN100 during registration | |
| Adding a space: "JOIN 100" | Code not recognized | Type it as one word: JOIN100 | |
| Lowercase: "join100" | May be rejected on some screens | Match the capitalization exactly | |
| Using an expired promo code | Invalid code error | Use JOIN100 — always active | |
| Ignoring the pre-filled link | Code field stays empty | Check the field is filled before confirming |
FOMO vs other copy trading apps: codes and fees
If you trade on Solana or BSC, you may be choosing between several apps. Here is how the referral codes and typical fee structures compare:
| Tool | Referral code | Signup link | Typical fee benefit | |
|---|---|---|---|---|
| FOMO | JOIN100 | fomo.family/r/JOIN100 | 10% off trading fees | |
| GMGN | COPYHQ | gmgn.ai/r/COPYHQ | Fee rebate on trades | |
| Photon | COPYHQ | photon-sol.tinyastro.io/@COPYHQ | Fee rebate on Solana trades | |
| Axiom | rebatehq | axiom.trade/@rebatehq | Trading fee rebate | |
| Runnr | TRADEHQ | mobile.runnr.trade/@TRADEHQ | 10% off trading fees |
FOMO stands out for social copy trading on Solana and BSC: you follow traders, their trades execute in your account automatically, and you can broadcast your own trades to build a following and earn a share of the fees your followers generate.
Is using a referral code safe?
Yes. A referral code only changes the fee you pay — it does not give anyone access to your funds, your account, or your trading history. The only things to watch for:
- Only sign up through the official domain (fomo.family) — phishing sites copy the design of trading apps.
- Never share your seed phrase or API keys with anyone claiming to "activate" a code.
- A code never requires a payment. If someone asks you to pay to receive a referral code, it is a scam.
