§ 01b · Live-to-Earn — a different category
Move-to-Earn pays for steps in its own token. Live-to-Earn is a different product altogether: eight precision sensors, a daily WVI score, USDT from a multi-chain pool. Not a competitor, not a successor — a separate category. The table below shows exactly where the line runs.
| Criterion | Live-to-Earn (Wellex) | Move-to-Earn (StepN, Sweatcoin, Walken) |
|---|---|---|
| What is tracked | Full wellness signal — sleep, HRV, SpO₂, stress, temperature, activity | Steps only (or GPS-tracked movement) |
| What is measured | Body readiness (WVI 0-100), longevity biomarkers | Calories burned via steps |
| Hardware | Wellex band with 8 precision sensors ($49) | Phone IMU / NFT sneakers $1K-$10K / NFT character |
| Signal accuracy | r=0.90 vs clinical ECG (peer-reviewed) | Phone IMU / GPS — no clinical validation |
| Payout currency | USDT (USD-pegged stablecoin) | Project's own token (GMT, SWEAT, WLKN) |
| Yield source | Multi-chain USDT staking pool, Halborn-audited | New-token emission (often inflationary) |
| Product category | Wellness wearable + DeFi yield | GameFi / fitness-game |
| User goal | Live longer, stay healthier | Earn more from walking |
Move-to-Earn asks "how far did you walk today?". Live-to-Earn asks "how ready is your body today, and how much did your WVI earn this month?" — different question, different physiology, different business model. Wellex doesn’t try to be a better Move-to-Earn — it’s a different thing entirely.
§ 01c · Decision shortcut
Each device wins on a specific axis. Below is the honest cheat-sheet — if your day looks like the line on the left, the device on the right is the right call.
I check notifications more than my pulse.
Built for connectivity, not recovery.
I optimise sleep above everything else.
Best-in-class sleep ring, lightest wear.
I push hard and need strain coaching.
Athletic load + recovery, subscription-only.
I want a doctor-grade longevity programme.
$50k a year, but only one of these is in your hand every day.
I want a calm, screen-free band that pays me back.
One score, one action, real USDT yield.
§ 02 · The one-line difference
Three things no competitor can say about itself, or copy without rebuilding the business model.
§ 01 · Transparent yield
0 – 20%
USDT · WVI-tied APY
The only wellness device that pays users back. Real multi-chain staking, paid in USDT, gated by your own WVI. No token.
§ 02 · Wellness-first, not fitness
100%
Longevity filter on every decision
Oura optimises sleep. Whoop optimises strain. Apple optimises notifications. Wellex optimises the question: will this extend the user's life?
§ 03 · One number, not ten tabs
1
Daily WVI · 0 – 100
Ten biometric streams compress into one score on your phone. No dashboards. No chart reading. One sentence of guidance a day.
Each bar is a criterion from the matrix above. Wellex fills 100%; the competition fills what they can honestly claim.
§ 03 · Deep dives
Recovery tracking that costs $199–$359/yr — or one that pays you back.
Ring or bracelet, insight or income. Prices, batteries, philosophy.
Buy-once sports computer vs subscription wellness that earns USDT.
Attention economy vs health economy. Why we're not competing.
Made your choice?
The bracelet that guides you to better sleep, sharper recovery, and one clear direction a day. Starting at $49. The only one that pays you back.
