Fomo App Referral Code JOIN100 – and the 10% Trading Fee Discount
Updated 25 September 2026 · 7 min read
What is the FOMO app referral code?
The FOMO app referral code is JOIN100. Add it when you create your FOMO account and your trading fee gets a 10% discount: instead of 0.50% you pay 0.45% per trade, on every trade you make.
Most people pick a crypto trading app based on the coins it lists or how the screens look. The number that quietly decides how much you keep is the fee you pay on each buy and sell. On FOMO that fee is simple and flat, and the one moment you can lower it is during sign-up. This guide covers what JOIN100 does, how much it saves at different trading sizes, how to apply it without mistakes, and how FOMO stacks up against other ways to trade crypto.

What FOMO actually is
FOMO is a mobile app for crypto trading with a social layer on top. You browse a feed of real wallets, see their open positions and results, and follow the traders you like. Whenever someone you follow buys or sells, you get a notification straight away. You then decide yourself whether to jump in, which means you can get in early on the coins they are buying — you stay in charge of every trade.
The app works across Solana, BNB Chain and EVM networks and is non-custodial, so the funds sit in a wallet you control. For a full breakdown of the features, read our FOMO app review.
How much JOIN100 saves you
Because you pay the fee on every buy and every sell, the discount grows with how much you trade. Here is what the difference between 0.50% and 0.45% looks like per month:
| Monthly trading volume | Fees at 0.50% | Fees with JOIN100 | You keep |
|---|---|---|---|
| $2,000 | $10.00 | $9.00 | $1.00 |
| $10,000 | $50.00 | $45.00 | $5.00 |
| $30,000 | $150.00 | $135.00 | $15.00 |
| $75,000 | $375.00 | $337.50 | $37.50 |
| $150,000 | $750.00 | $675.00 | $75.00 |
Someone trading $30,000 a month keeps around $180 extra per year, just for typing six characters at sign-up. Active traders who act on lots of alerts usually hit these volumes faster than they expect, since a single coin can mean several buys and sells.
How to apply code JOIN100 step by step
- Open the FOMO referral link on your phone. The code is filled in for you.
- Or download FOMO from the App Store or Google Play and tap sign up.
- When asked for a referral or invite code, type JOIN100.
- Finish creating your account and set up your wallet.
- Add funds on the network you want to trade on.
- Before your first trade, check that the fee shows 0.45% instead of 0.50%.
There is no minimum deposit linked to the code and the discount does not run out after a trial period. For a shorter version of these steps, see the FOMO referral code quick guide.
Common mistakes to avoid
- Signing up first, adding the code later. Not possible — the code only counts during registration.
- Typos. The code is JOIN100: four letters, then the number 100.
- Old codes from forums. Random codes online are often expired. JOIN100 is active.
- Making a second account. Stick to one account that has the discount from the start.
FOMO compared with other crypto trading apps
| App | Type | Fee per trade | Follow traders | Mobile |
|---|---|---|---|---|
| FOMO | Social trading app | 0.45% with JOIN100 | Yes, with instant alerts | Mobile first |
| Axiom | Trading terminal | ~1% | No, manual trading | Browser |
| Photon | Web terminal | ~1% | Limited | Browser |
| Exchange app | Centralised exchange | 0.10%–0.60% | No | Yes |
Terminals like Axiom suit people who sit at a desktop and trade by hand. FOMO is the easier fit if you want to follow what strong traders do and react from your phone. Learn more about how FOMO social trading works.
Is FOMO worth it with the referral code?
If you trade memecoins or on-chain tokens and like seeing what other traders do in real time, FOMO with JOIN100 gives you the social feed, instant alerts and a lower fee in one app. Keep in mind that following a trader does not guarantee profits — they lose trades too, and fast coins can move before your order fills. Trade with money you can afford to lose.
