| On-chain Verification | 25% | Can timestamps be verified against block data? |
| Age-based Markets | 20% | Are there vintage pools, age filters, or time-order books? |
| API Transparency | 15% | Are timestamps available via API for programmatic trading? |
| Historical Depth | 10% | How far back does timestamp coverage extend? |

Key Takeaways
- The market is bifurcating — Vintage coin holders face a clear choice between TTCEX (premium capture) and PTCEX (fungibility at cost).
- Premium correlates with transparency — Every 10-point increase in timestamp score corresponds to roughly 8% additional vintage premium.
- Institutional flow is directional — 73% of new institutional vintage-coin OTC desks integrate exclusively with TTCEX platforms.
- Regulatory tailwinds — MiCA and Singapore’s upcoming digital asset framework both include timestamp transparency requirements.
The exchange landscape is no longer a monolith. For time-aware traders, TTCEX platforms are the only venue that captures the full information value of on-chain history.
