BidAskBit: When the Exchange Let You Deposit But Never Let You Withdraw

BidAskBit looked like any mid-tier exchange — until a Dublin architect tried to withdraw. Then came a ‘capital-gains clearance fee,’ an ‘anti-money-laundering hold,’ and silence. €54,200.

Point of Entry

A Dublin architect opened an account with BidAskBit after seeing it promoted as a low-fee exchange. Deposits cleared instantly and the interface looked the part.

He traded for weeks, watching a healthy balance grow, before he tried to take any of it out.

Where Custody Broke

The withdrawal triggered a ‘capital-gains clearance fee,’ then an ‘anti-money-laundering hold’ that could only be lifted by depositing more. Each step moved the goalposts.

When he refused to send more, support stopped replying and the balance became unreachable.

“Depositing was instant. Withdrawing turned into a wall of fees I was told I had to pay first.”— Cian B., Dublin

The Recovery Ledger

1. L01Intake & capture. We recorded every deposit to BidAskBit, the account screenshots, and the fee demands blocking the withdrawal.
2. L02On-chain trace. The BTC and USDT deposits consolidated into wallets we tracked to a regional off-ramp.
3. L03Off-ramp identification. The withdrawal-block had actually kept much of the balance pooled rather than dispersed.
4. L04Attestation & freeze. We filed a documented freeze request with the receiving exchange before the funds moved.
5. L05Recovery. The freeze caught most of the Bitcoin tranche; a smaller USDT portion had already been routed away.

Breach Signatures

• An exchange where deposits are instant but withdrawals trigger new conditions.
• A ‘tax,’ ‘clearance,’ or ‘AML’ fee payable only by depositing more.
• Pressure and shifting requirements once you try to cash out.
• No verifiable regulation or registered entity.
• Support that goes silent the moment you stop funding.
