Bitcoin fell as much as 10% on Thursday, hitting its lowest level in nearly three weeks as the popular cryptocurrency was hit with a double whammy that tarnished faith in its user base.

First, Treasury Secretary nominee Janet Yellen suggested ‘curtailing’ bitcoin during her confirmation hearing on Wednesday because of its suggested use in illegal activities, and secondly, an unconfirmed report by BitMEX research suggested a critical shortfall of the name “double spending” occurred in the bitcoin blockchain.

Double spending is when a bitcoin owner can spend the same bitcoin twice. It’s a scary and dire scenario for the digital asset, and the blockchain was thought to have resolved the issue when Satoshi Nakamoto published the Bitcoin White Paper in 2009.

Early attempts to launch a digital currency system were ultimately hampered by weaknesses that could have enabled double spending and undermined trust in the system.

BitMEX Research tweeted on Wednesday, “It seems as though a small double spend of about 0.00062063 BTC ($ 21) has been found.”

At first, it appeared that the assumed double spend was actually an RBF transaction, and that is when an unconfirmed bitcoin transaction is replaced by a new transfer paying a higher fee. But ForkMonitor has said of the alleged double spending transaction, “No lumps (RBF) found.”

BitMEX went on to tweet, “A loss chain transaction sent 0.00062063 BTC to the address 1D6aebVY5DbS1v7rNTnX2xeYcfWM3os1va, and only 0.00014499 BTC sent a transaction in the winning chain that expended the same inputs to this address.”

If the $ 21 double spend actually happened, it could be a fatal blow to the popular cryptocurrency in the sense that the Nakamoto deficit that went into solving it actually remains vulnerable and could crumble confidence in the asset.

Institutional investors, meanwhile, continue to be exposed to bitcoin. According to an SEC filing on Wednesday, BlackRock has enabled two of its mutual funds to invest in the cryptocurrency.
