The initial transaction used a “default or conservative” fee setting. The user’s first RBF attempt doubled the fee and altered the output address. But instead of confirming either of these transactions, a final RBF with a dramatically higher fee overrode them, causing the entire amount of the change — 0.75 BTC — to be included as miner reward.

Satoshi Error or Bug in Wallet Script?

According to Anmol Jain, VP of Investigations at AMLBot, the user may have made a simple yet costly mistake in fee calculation. Jain suggested the user likely meant to enter 30.5692 sat, but accidentally typed 305,692 sat — or confused sat/vB with total satoshis.

Another theory is that an automated wallet script contained a miscalculation. Some wallets allow fee settings in sats/vB, and such confusion can arise if the system interprets a small value as too low and prompts the user to increase it. Jain explains:

“User types 305000 thinking it’s 30.5 sat/vB, but the wallet applies 305,000 sat/vB — which is insane.”

The mistake caused the wallet to treat a full UTXO of nearly 0.75 BTC as a transaction fee, likely due to not properly updating the change address or misreading the transaction structure. Both earlier transactions remained unconfirmed while the highest-fee version went through.

RBF: Flexible Feature or Dangerous Tool?

Replace-by-fee is a controversial but core feature in Bitcoin. It allows users to replace unconfirmed transactions with higher-fee versions. Miners, motivated by profit, are expected to confirm the version that offers a higher reward.

This mechanism has sparked debate. In 2019, Bitcoin Cash advocate Hayden Otto claimed RBF enabled double-spending. Bitcoin Cash removed RBF support and claimed unconfirmed transactions on its network were final and trustworthy.

Despite this, RBF-like behaviors have occurred on Bitcoin Cash as well, showing that this feature is more a result of blockchain dynamics than a standalone switch.

OKX is reportedly moving thousands of Bitcoin Unspent Transaction Outputs (UTXOs) into its hot wallets. This activity is taking place with fees that are more than 10 times the average fee observed in the past 24 hours.

The Bitcoin network is currently experiencing significant congestion, with a staggering number of transactions waiting for confirmation in the mempool. As a result, users are being forced to pay over 500 satoshi per byte to have a transaction processed immediately, which translates to around $50-100 for a typical transfer.

This exorbitant fee rate means that a significant portion of the Bitcoin that OKX is trying to consolidate is going to miners. For example, a fee of $15,000 was paid to consolidate UTXOs with a total value of just $48,000 in one transaction, representing over 30% of the total value.

The Bitcoin network is currently struggling with over 330,000 unconfirmed transactions, and memory usage has risen to 1.35 GB. Under these conditions, OKX is suspected of consolidating and batching its user wallets, a move that has caught the attention of many in the cryptocurrency community.
