There are still 14 victims of the massive Twitter hack who could still get their Bitcoin back.
These victims have sent Bitcoin to a hacker address, however Your transactions have not yet been confirmed on the Bitcoin network. They are currently hanging in the balance or in the Bitcoin mempool. These transactions appear to be unconfirmed after many hours because the senders set a very low transaction fee that is not attractive to miners.
Bitcoin core developer Wladimir van der Laan confirmed this to Cointelegraph. “Miners choose the highest rate transactions, but they may also have a minimum rate below which they won’t undermine transactions at all.”said.
For example, a transaction suggested a rate of 2 satoshis per byte. The expected delay for a transaction with such a small fee is between 35 and 780 minutes. As van der Laan explained, they must never be processed:
“They can be processed if there is really nothing more attractive in the mempool (For example, some weekend downtime with small new transactions?), But they may never be processed and simply forgotten. “
How these victims can get their money back
Victims whose transactions migrate in the mempool can send the same bitcoin (with the same inputs) to a different address, which they control with higher fees. Even if the miners are ever allowed to process their original transactions, they will not be confirmed as the Bitcoin protocol checks the validity of the entries. Since these tickets would have been issued, the original transactions would be rejected.
Hopefully at least some of the victims will learn their lesson without paying the price.
