A Taiwanese netizen posted a bounty message on Threads yesterday (13th), stating that he realized he had transferred 1.5 Bitcoins into an international wallet (Huobi) five years ago. Now, with the price of Bitcoin skyrocketing, he finds his wealth locked away in an inaccessible safe due to the loss of his private key. (Background: Internet celebrity MrBeast cried after his Bitcoin private key was stolen, relieved that the thief was too foolish to take all his BTC) (Background information: This girl challenged to live using only Bitcoin for ‘21 days’ on Isla Mujeres in Mexico) The Taiwanese Threads user ‘weiwei.179’ posted a bounty message yesterday (13th), recounting that he realized he had transferred 1.5 Bitcoins into an international wallet (Huobi) five years ago. Now, with Bitcoin’s price soaring, he finds his wealth locked in a safe he cannot open due to the loss of his private key. This netizen added that he used Huobi wallet for transactions at that time and only transferred out USDT and ETH, believing he had liquidated his holdings. To his surprise, the Bitcoins were still quietly sitting on-chain. Faced with the dilemma of ‘having an address but no key,’ he was willing to pay 360,000 New Taiwan Dollars to anyone who could help him recover his key, emphasizing that he would not provide his account or personal information to prevent fraud. Help requests on Threads sparked the ‘Keyless Gate’ A netizen described on Threads that while checking the lock-up earnings on the MAX platform, he accidentally discovered his Bitcoin purchase record from 2020. At that time, the price of one Bitcoin was less than 300,000 New Taiwan Dollars, and he had just made a casual investment. Now, with the value multiplied tenfold, he cannot transfer out the 1.5 Bitcoins because the handwritten note with the key has gone missing. In despair, he left the question: ‘If the paper cannot be found, is there still a way to decrypt it?’ The irreversible technical reality of private keys Scanning through the comments, the answers were almost all negative. Many netizens commented that if the private key cannot be found, it would be unsolvable. Some even bluntly stated after seeing the netizen’s plea: ‘Thanks for providing fewer Bitcoins in circulation, now there’s 1.5 less…’ We know that Bitcoin private keys are encrypted using elliptic curve cryptography, with combinations reaching 2 raised to the power of 256. Brute force attacks are akin to picking out a specific grain of sand in a desert; currently, no computer can accomplish this task. Additionally, many newbies often confuse wallet passwords with private keys. Wallet passwords are only used to unlock the software interface; if forgotten, recovery attempts can still be made. The private key, however, directly relates to the control of on-chain funds. Once lost, it is like a bank destroying its seal and identification card, with no replacement window available. The capabilities and limits of professional recovery services It is also worth mentioning that market recovery companies for crypto assets, such as Covasecure or Puran Crypto Recovery, often target cases of ‘forgotten passwords’ or ‘missing a few words from the mnemonic phrase.’ Such situations can narrow down the search scope, with a success rate of up to 90%. However, for those who have completely lost their private keys, they usually have to decline assistance because if they could forcibly crack it, the security of the blockchain would no longer exist. Because of this, some criminals have also seized upon investors’ anxiety, claiming they can ‘reproduce private keys’; their trick is often to collect a high deposit before dragging out the process. Experts remind that legitimate companies usually operate on a success fee basis and will first check the on-chain address and possible backup traces before collecting any payment. Proper storage is the only answer This incident once again proves the harsh truth in the Web3 world: ‘If it’s not your private key, it’s not your money.’ Cryptocurrencies have no customer service center and no lost item reports. The only effective defense line is to back up and store it properly in advance. Searching for various security advice, many experts remind investors to write their 12 to 24 mnemonic words on two fireproof papers and store them in different safes. At the same time, prepare a hardware wallet, set up a PIN and two-factor authentication, and check it annually to ensure peace of mind. As for this Taiwanese netizen, perhaps the only thing he can do at this stage is to rummage through boxes to find the old note or recall whether he took any reminder photos. The chances of recovering what was lost are slim, but the sooner he acts, the less likely the clues will disappear. If he forgot his wallet password, there is still a chance to find an expert to crack it. However, if he remembers the private key, it is indeed very difficult to recover. In the end, I wish this netizen luck in finding the key to unlock that 1.5 Bitcoins.
