What the main code actually does
Fomo charges a trading fee on every swap your account executes. That includes trades you place yourself and trades copied from the traders you follow. Without a referral code the fee is 0.50% of each trade. When you sign up with the main code JOIN100, Fomo takes 10% off, so you pay 0.45% instead.
Ten percent sounds small on paper. On a copy trading account it is not. A follower who copies several traders can execute dozens or even hundreds of swaps per month, and the fee applies to each one. Cut the fee by 10% and the savings compound with every executed trade. You can test your own numbers in our copy trading fee calculator to see the difference over a month or a year.
Savings per trade with JOIN100
| Trade size | Fee without code (0.50%) | Fee with JOIN100 (0.45%) | You save | |
|---|---|---|---|---|
| $100 | $0.50 | $0.45 | $0.05 | |
| $250 | $1.25 | $1.13 | $0.12 | |
| $500 | $2.50 | $2.25 | $0.25 | |
| $1,000 | $5.00 | $4.50 | $0.50 | |
| $2,500 | $12.50 | $11.25 | $1.25 | |
| $5,000 | $25.00 | $22.50 | $2.50 | |
| $10,000 | $50.00 | $45.00 | $5.00 |
A single trade does not look like much. The next table shows why the code matters over a year.
Savings per year
The numbers below assume a steady account that trades the same average size all year.
| Trades per month | Average trade size | Yearly fees without code | Yearly fees with JOIN100 | Yearly savings | |
|---|---|---|---|---|---|
| 10 | $500 | $600 | $540 | $60 | |
| 25 | $500 | $1,500 | $1,350 | $150 | |
| 10 | $2,000 | $1,200 | $1,080 | $120 | |
| 25 | $2,000 | $3,000 | $2,700 | $300 | |
| 50 | $1,000 | $3,000 | $2,700 | $300 | |
| 100 | $1,000 | $6,000 | $5,400 | $600 |
One hundred trades a month is realistic for an active copy trader who follows fast-moving wallets. At that volume the main code saves $600 per year — real money that stays in your account instead of leaking away to fees.
How to sign up with the FOMO app referral code
| Step | Action | What to check | |
|---|---|---|---|
| 1 | Open https://fomo.family/r/JOIN100 | The link carries the code for you | |
| 2 | Create your account | Use your email or wallet sign-in | |
| 3 | Find the referral code field | It shows during signup | |
| 4 | Confirm the field says JOIN100 | If it is empty, type the code exactly | |
| 5 | Finish registration | The 10% discount is now attached | |
| 6 | Deposit and make your first trade | The fee should read 0.45%, not 0.50% |
The whole process takes a few minutes. The only step people get wrong is number 4: they rush past the code field, or they type the code after the account already exists. The discount can only attach before your first trade, so check the field twice.
Where to enter the code
There are two places the main code can be applied:
- Through the referral link. Open https://fomo.family/r/JOIN100 and the code travels with the link. This is the safest method because there is nothing to type.
- Manually during signup. If you open the Fomo app or website directly, look for the referral or promo field on the registration screen and enter JOIN100 exactly as written — capital letters, no spaces.
If neither field appears on your screen, complete the signup and check the fee on your first trade before you size up. If the fee shows 0.50%, the code did not attach — see the fixes below.
How Fomo compares with other copy trading apps
Fomo is not the only copy trading app, and it helps to see the fee picture side by side. We cover the alternatives in our tools directory and in the individual guides, but here is the short version.
| App | Copy trading | Referral discount | Typical focus | |
|---|---|---|---|---|
| Fomo | Yes | 10% off fees with JOIN100 | Multi-chain copy trading | |
| GMGN | Yes | Bonus credits via referral | Solana memecoins | |
| Photon | Yes | Rebate through referral link | Fast Solana execution | |
| Axiom | Yes | Rebate through referral link | Solana and beyond |
Every app on this list has its strengths. The reason Fomo with JOIN100 is our top pick is simple: the discount is a straight 10% cut on trading fees, confirmed on the fee screen, on every trade, with no conditions to track. If you want a second opinion before you commit, our guide to the best crypto copy trading tools breaks down the fees in more detail.
Common mistakes and how to fix them
| Mistake | What happens | How to fix it | |
|---|---|---|---|
| Typo in the code | Discount does not attach | Re-enter JOIN100 exactly, capital letters | |
| Entering the code after the first trade | Discount cannot attach retroactively | Contact Fomo support before trading more | |
| Using a random code from a video | Code may be inactive | Use the main code JOIN100 | |
| Skipping the referral link | Manual entry, more room for error | Open https://fomo.family/r/JOIN100 | |
| Assuming the fee dropped without checking | You may still pay 0.50% | Check the fee screen on your first trade |
The last row is the one that costs people money. After signup, place a tiny test trade first and look at the fee line. It should read 0.45%. If it reads 0.50%, stop and fix the code before you trade at full size.
Who benefits most from JOIN100
Every Fomo user benefits from the discount, but three groups gain the most:
- Active copy traders. If you follow several traders and copy every position, your monthly trade count climbs fast. The more swaps you execute, the more the 10% discount is worth.
- Larger accounts. Fees scale with trade size. On a $10,000 trade you save $5 every time; over a year of active trading that is hundreds of dollars.
- Small accounts building up. Early on, every dollar saved is a dollar that stays invested. Keeping fees low from day one gives a small portfolio a better chance to grow.
Even if you only place a handful of trades a month, the code costs you nothing and takes one minute to apply. There is no reason to skip it. Our guide to how copy trading works on Fomo explains how the copied trades add up if you want the mechanics.
Your first week with the discount
| Day | Task | Goal | |
|---|---|---|---|
| 1 | Sign up with JOIN100 and verify the 0.45% fee | Confirm the discount is live | |
| 2 | Browse traders and check their track records | Build a shortlist | |
| 3 | Follow one trader with a small allocation | Test copy trading with low risk | |
| 4 | Review the executed trades and fees | See the discount applied on copies | |
| 5 | Add a second trader if the first looks good | Diversify your copy sources | |
| 6 | Check your fee total for the week | Compare with the 0.50% rate | |
| 7 | Set rules for stops and maximum allocation | Protect your capital before scaling up |
A calm first week beats a rushed one. The discount is permanent once attached, so there is no need to rush your trading decisions to use it before it runs out. Take the time to pick traders with consistent records instead of chasing the biggest recent winner.
Final checklist before your first trade
- The signup went through https://fomo.family/r/JOIN100, or the code field showed JOIN100.
- Your first trade fee reads 0.45%, not 0.50%.
- You set a budget you are comfortable losing on copy trades.
- You picked traders with a history, not just a hot week.
- You know where the stop or exit rules are for each trader you follow.
Five checks, two minutes, and your account is set up the right way from the start. For a broader view of trading tools and fee strategies outside Fomo, https://appforcryptotrading.com/ is a useful independent resource.
