In brief

  • A California court has decided that Coinbase is not obligated to pay out Bitcoin Gold generated in a 2017 Bitcoin fork.
  • Plaintiff Darrell Archer sued the company after demanding Bitcoin Gold that could have been generated from his 350 Bitcoin held on Coinbase.
  • Crypto lawyer Justin Wales sees the ruling as a milestone for digital asset custody case law in the US.

Crypto lawyer Justin Wales has used a recent California court ruling to drive home how important the notion of “not your keys; not your coins” can be.

In a recent Twitter thread, crypto lawyer Justin Wales outlined recent analysis from Justia in the Archer v. Coinbase court case.

Wales, co-chair of Carlton Fields’ virtual currency practice group, said the court’s decision elevates to case law the crypto adage “not your keys, not your coins”—in other words, if Bitcoin or other digital currencies are stored in a wallet with private keys you don’t control, just about anything can happen to them, and the law can't protect you.

In the case, plaintiff Darrell Archer sued Coinbase for breaching their user agreement after the company refused to provide him with Bitcoin Gold generated in a fork of Bitcoin. Archer had 350 Bitcoin stored on Coinbase at the time of the fork, which would have generated Bitcoin Gold worth approximately $159,000 at its peak value.

Archer had handed control of his Bitcoin over to Coinbase, and as Wales pointed out, “Accessing your forked coins is only guaranteed if you hold your own private keys!”

The California First Court of Appeals found Coinbase's user agreement created no obligation to hand over the Bitcoin Gold. Coinbase cited a number of reasons for not supporting the Bitcoin Gold fork in the way it had supported forks like Bitcoin Cash in the past, including the inability to review the closed-source Bitcoin Gold code.

The significance of such a ruling was not lost on Wales, who noted other jurisdictions around the US are likely to follow California’s lead when it comes to digital asset custody battles.

“If you choose to let someone hold your keys, this case reinforces how important It is to read the user agreement and understand what it is you are agreeing to,” Wales told Decrypt.

“For Archer, Coinbase had complete discretion on what forks to offer. This is significant since Bitcoin and other crypto are evolving and we don’t know what type of forks will be created, for what reason, or what will ultimately gain significant market share.”

“Not your keys, not your coins” is typically used in reference to crypto exchanges or third-party investment managers that, through carelessness or malice, have on occasion lost millions in user funds to exploits or theft.

And even though Coinbase is trusted by millions of crypto users, it’s undeniable that even in the best of hands, sending crypto to wallets you don’t control can lead to missing out on potentially sizable gains.
