FOMO App Referral Code JOIN100 — Quick Answer
| Question | Answer | |
|---|---|---|
| What is the FOMO referral code? | `JOIN100` | |
| What does it give you? | 10% discount on trading fees | |
| Who can use it? | New users, entered during signup | |
| Where do you enter it? | The referral / invite code field during registration | |
| Referral link | fomo.family/r/JOIN100 | |

What Does the JOIN100 Referral Code Give You?
The JOIN100 code is not a bonus balance or a free token drop. It is a fee discount, and that matters more than most beginners realize. On FOMO, every trade you place — whether you trade manually or copy another trader's broadcast — carries a trading fee of roughly 0.50% per trade. With JOIN100 applied, eligible users pay about 10% less on those fees, bringing the effective cost per trade down to roughly 0.45%.
Here is what that means in practice:
- Lower cost per trade. Every swap, buy, or copy trade costs slightly less, trade after trade.
- Compounding savings. Active copy traders execute dozens or hundreds of trades per month. A 10% fee reduction compounds into meaningful money over a year.
- No strings on your trading. The discount changes what you pay, not what you can trade. Same markets, same broadcasts, same tokens.
- Immediate effect. The discount applies from your very first trade after signup — no waiting period or minimum volume.
The discount only helps you if you actually apply the code during signup. FOMO cannot retroactively attach a referral code to an account that was created without one, so it is worth getting right the first time.
Where to Enter the FOMO Referral Code (Step by Step)
There are two ways to sign up to FOMO with JOIN100: through the referral link or by typing the code manually. Both produce the same result.
Option 1: Use the referral link (easiest)
| Step | Action | |
|---|---|---|
| 1 | Open fomo.family/r/JOIN100 in your browser | |
| 2 | Tap Sign up and create your account (email or wallet) | |
| 3 | The referral field is pre-filled with `JOIN100` — do not clear it | |
| 4 | Complete registration and confirm your email | |
| 5 | Your fee discount is active from your first trade |
Option 2: Enter the code manually
| Step | Action | |
|---|---|---|
| 1 | Open the FOMO app or fomo.family and tap Sign up | |
| 2 | Fill in your email and password | |
| 3 | Look for the field labeled Referral code, Invite code, or Promo code | |
| 4 | Type `JOIN100` exactly — codes are usually case-sensitive | |
| 5 | Finish registration and check that the discount is shown in your account settings |
On the FOMO mobile app
The flow is nearly identical on iOS and Android: tap Sign up, enter your details, then expand the "Have a referral code?" option if it is collapsed. Type `JOIN100`, confirm, and complete registration. If you signed up through an app store download instead of the referral link, the referral field is easy to miss because it sits below the main signup form — scroll down before submitting.
How Much Can You Save With JOIN100?
The 10% discount sounds small until you multiply it by realistic trading activity. Here is the math for a copy trader executing trades through FOMO's standard ~0.50% fee:
| Monthly trade volume | Fee without code (0.50%) | Fee with JOIN100 (~0.45%) | Yearly savings | |
|---|---|---|---|---|
| $1,000 | $5.00 | $4.50 | ~$6 | |
| $5,000 | $25.00 | $22.50 | ~$30 | |
| $10,000 | $50.00 | $45.00 | ~$60 | |
| $50,000 | $250.00 | $225.00 | ~$300 | |
| $100,000 | $500.00 | $450.00 | ~$600 |
Numbers assume the standard 0.50% fee and a full 10% discount; your exact rate may vary. If you want to run your own numbers, use our free crypto copy trading fee calculator — it compares FOMO's fees with other platforms and shows your break-even volume.

Referral Code vs Promo Code vs Invite Code: Same Thing?
People search for this code under different names, and on FOMO they all point to the same field:
| Term you might see | What it means on FOMO | |
|---|---|---|
| Referral code | The code a friend or creator shared — `JOIN100` | |
| Invite code | Same field, different label | |
| Promo code | Marketing name for the same signup discount | |
| Referral link | A URL like fomo.family/r/JOIN100 that pre-fills the code |
If a signup screen asks for any of these, `JOIN100` is the value to enter. There is no separate promo code that stacks on top of it.
FOMO vs Other Copy Trading Platforms (with Referral Codes)
If you are still choosing a platform, here is how FOMO compares with the other popular Solana and multi-chain copy trading apps — including the working referral codes for each:
| Platform | Chains | Standard fee | Referral code | Referral link | |
|---|---|---|---|---|---|
| FOMO | Solana, multi-chain | ~0.50% per trade | `JOIN100` | fomo.family/r/JOIN100 | |
| GMGN | Solana, BSC, more | ~1% per trade | `COPYHQ` | gmgn.ai/r/COPYHQ | |
| Photon | Solana | ~1% per trade | `COPYHQ` | photon-sol.tinyastro.io/@COPYHQ | |
| Axiom | Solana | ~0.9% per trade | `rebatehq` | axiom.trade/@rebatehq | |
| Runnr | Solana | Varies | `TRADEHQ` (10% off) | mobile.runnr.trade/@TRADEHQ |
You can compare all of these side by side on our crypto copy trading tools directory. If you trade on Solana specifically, our Axiom referral code and Runnr referral code guides cover those platforms in depth.
What If the Referral Code Is Not Accepted?
Occasionally the code field rejects input. The usual causes and fixes:
| Problem | Likely cause | Fix | |
|---|---|---|---|
| "Invalid code" message | Typo or wrong case | Re-type `JOIN100` exactly, all capitals | |
| No referral field visible | Field is collapsed | Look for "Have a referral code?" or "Invite code" link below the form | |
| Code field missing entirely | You opened the app directly, not via the link | Use the referral link instead | |
| Already signed up without a code | FOMO cannot attach codes retroactively | Contact FOMO support; otherwise the discount applies only to new signups | |
| Discount not reflected | Cached session | Log out, log back in, and check account settings |
The most common mistake is signing up first and looking for the code field later. FOMO's referral code must be entered during registration — it cannot be added afterward from account settings.
Tips Before You Start Copy Trading on FOMO
The fee discount is the easy part. Before you fund your account:
- Start small. Copy a trader with a modest allocation until you understand how broadcast copying executes in practice.
- Check the trader's history. FOMO shows past performance, but past results never guarantee future returns.
- Mind slippage. On fast-moving tokens, your copy trade may fill at a slightly different price than the broadcast trade.
- Budget for fees. Even at 0.45% with JOIN100, frequent trading adds up — size your positions accordingly.
- Never share your seed phrase. No referral code, admin, or support agent will ever ask for it.
