From the marginalia — the deposit pathway:

• Deposit confirmations from the claimant to Probtc.online’s receiving wallet at pro-btc.online.
• Forwarding-wallet pathway documented hop-by-hop with chain-of-custody hashes.
• Cross-chain bridge transactions where the operator routed value out of the deposit chain.
• Mixer or coin-join interactions, where applicable.
• Final off-ramp at a centralised exchange — the compliance counterparty named in the recovery filing.

The annotation continues — off-ramp endpoint:

• Probtc.online casefiles end at a centralised exchange — Bybit, KuCoin, OKX, or Gate.io are common; the casefile names the actual deposit address that received the consolidated funds.
• Off-ramp wallet for Probtc.online is matched against compliance and chain-analytics datasets the Professor reads daily.
• Compliance leverage applied to the named off-ramp for Probtc.online — the packet is delivered in compliance-desk format.
• Non-cooperative off-ramps trigger IC3 + state-AG + civil-discovery escalation on the Probtc.online casefile.

Recovery sequence — from on-chain reading to filed packet:

1. Triage on Probtc.online — submission read against a no-go checklist, written go/no-go returned to the claimant inside one business day.
2. Trace on Probtc.online — deposit pathway mapped across chains, captured with chain-of-custody hashes.
3. Identify on Probtc.online — off-ramp endpoint matched to a named exchange counterparty.

• Filings the Probtc.online packet supports — IC3, the appropriate state attorney general, the off-ramp’s compliance desk, and a civil-discovery overlay where dollar value justifies it.
