Cemetery / BitMEX
BitMEX
Derivatives exchange that pioneered the crypto perpetual swap; HDR Global Trading announced orderly closure effective 23 September 2026 04:00 UTC. New registrations stopped 23 July 2026; reduce-only from 26 August; users urged to close positions and withdraw. Post-closure login for balances/history remains with monthly custody fees if funds are left.
Quick answer
BitMEX is tracked in the CTD crypto project cemetery so former users can reconstruct venue history, claim status, and tax-relevant records. Start with CSV exports, account statements, explorer history, and any claim-portal documents before asking software or an accountant to review the case.
1. History reconstruction
Where leftover records may still live.
CSV / statements: Download trade / wallet history before and after Closure Time while account access remains; keep force-close fills.
Software: Perpetual / derivative PnL lines often need special event mapping — do not treat as simple spot trades.
- Force-closed positions at wind-down may create taxable realizations depending on jurisdiction.
- Post-closure custody fees (USD 50 or 1% p.a., monthly) — document fee deductions.
