Hi,
Apologies for asking for help here, but hopefully this problem is interesting enough to a few people in the forum to think through it.
For context, this is a work problem for someone close to me who knows nothing about BTC. I know enough to help a bit: I've used Coinbase and my parents actually were huge into it so I understand the broad structure. But not enough to completely understand/fix the problem here.
So...a client of the person close to me decided in 2023 to buy BTC through a Bitcoin Depot ATM. (Yes, I know, terrible way to do it, and gives a sense of the technical understanding of the client.) Bitcoin Depot since has filed for bankruptcy, and all its systems are offline.
I know the client had to get a digital wallet to send the crypto to. My guess (and I will update if/when I know better) is that the client used the wallet on the Bitcoin Depot app. Highly skeptical they understood cold storage or anything like that.
So the Bitcoin Depot app is also offline. We have a picture of the original ATM receipt showing the BTC address. We have nothing else. Google search suggests that there might be data in the app stored locally to perhaps get to the key or the seed phrase — but I'm unfamiliar with precisely how those wallets work and if that indeed would be the case. (For what it's worth, Bitcoin Depot said it never custodied any crypto: it took cash at the ATM and then sent the crypto into the user's wallet. So it's not a case of "they're bankrupt and maybe they stole the crypto", unless there's an unreported scandal there.)
I'm also not entirely sure what we do with the private key and/or seed phrase should we find it. We can't just use the app to send the crypto onward, it's offline.
Were you the person close to me, what would your strategy be here? Obviously, step one is trying to find out what digital wallet is being used, but can anyone provide some thoughts on what step two (and onward) might/should be?
Thank you for reading.
