Grayscale GBTC Trust, the largest legal holder of BTC, refuses to provide any Proof of Reserve.
To begin a community lead effort at transparency for the GBTC holdings, we have taken steps to ID likely GBTC addresses and balances based on public info and blockchain forensics.
TLDR
- Using public data and chain forensics, we have attributed 432 addresses holding 317,705 BTC to likely GBTC custody activity.
- This total is ~50% of GBTC reported current holdings.
- Additional work is necessary to ID the remaining addresses.
In early August, the remnants of ETH seized from the multibillion dollar PlusToken scheme awoke on-chain for the first time since 2021.
Over the last 24h about 7k ETH of the remaining 542k ETH ($1.3b) was sent to exchanges indicating intent to begin selling the remaining tokens.

In this analysis we use additional on-chain forensics to CONFIRM the approximate 633k BTC balance held by G(BTC) at Coinbase Custody.
Which begs the question, why does Grayscale refuse to disclose their on-chain holdings?

Adding another 444 BTC to the previously reported 4.6k ETH from yesterday's @cryptocom hack.
Still no acknowledgement of loss, despite large outflows from the custodial wallet into ETH's Tornado Cash and a well known BTC tumbler (as detailed below).
In case you missed it, GBTC claims they cannot provide a Proof of Reserve due to “security concerns”.
Maybe this is a non-disclosure policy enforced by Coinbase Custody.
Maybe it’s deliberate obfuscation by Grayscale.
6) Coinbase frequently performs on-chain validation. Due to security concerns, we do not make such on-chain wallet information and confirmation information publicly available through a cryptographic Proof-of-Reserve, or other advanced cryptographic accounting procedure.
I’ve been seeing a lot of Twitter FUD opining on miner capitulation in the last few days.
This got me thinking… could the selling by the PlusToken scammers have had an abnormal effect on this market cycle?
Sparked by the tx graph in this tweet, we have ID’d the Alameda BTC wallet cluster and likely Alameda FTX deposit address.
The likely FTX Intl deposit address processed 3300 BTC via FTX US on 6-Nov during the bank run, despite FTX management claims of “segregated entities”.
On July 29, 2019 Grayscale claims to have owned about 240k BTC.
Looking at the XAPO cluster for corresponding activity, we see a massive spike in volume from a handful of transactions that are likely the Grayscale custody rotation mentioned above.
