This handful of ETFs have certainly been busy since they launched eight months ago. Current data shows that these 12 funds now hold about 4.68% of the total 19.76 million bitcoins in circulation, amounting to a whopping 924,768.09 BTC—valued at over $60 billion based on today’s exchange rates.

When these funds first hit the market, Grayscale’s GBTC was sitting on over 620,000 BTC, but now it holds 220,820.34 BTC. That’s a substantial reduction, with more than $20 billion worth of bitcoin leaving Grayscale’s trust, likely ending up in the hands of the newer spot bitcoin ETFs.

Blackrock’s ETF, IBIT, now boasts a hefty 365,310.38 BTC—making up a solid 39.5% of the total 924,768.09 BTC held by the 12 funds. That means IBIT alone accounts for 1.85% of all the bitcoins currently in circulation. Grayscale’s GBTC, while still significant, holds the second-largest position among these ETFs with 220,820.34 BTC in its reserves.

The numbers reveal that GBTC commands 23.88% of all bitcoin held by the funds, which translates to 1.12% of the 19.76 million bitcoins circulating globally. Hot on Grayscale’s heels is Fidelity’s FBTC, sitting on 178,334.14 BTC.

This gives FBTC 19.28% of the total held by all 12 funds and 0.90% of the circulating bitcoin supply. The remaining ETFs each hold under 50,000 BTC. Leading the pack is Ark Invest and 21shares’ ARKB fund with 47,599 BTC, followed by Bitwise’s BITB at 39,588.07 BTC.

Not far behind is Grayscale’s Bitcoin Mini Trust, which currently manages 33,752.77 BTC. The other ETFs hold even smaller bitcoin reserves. Vaneck’s HODL leads this group with 11,482.53 BTC, followed by Valkyrie’s BRRR at 8,982.53 BTC.

Invesco and Galaxy’s BTCO comes in with 7,941 BTC, while Franklin Templeton’s EZBC manages 7,103.85 BTC. Lower on the list, Wisdomtree’s BTCW holds 3,705.48 BTC, and Hashdex’s DEFI wraps things up with just 148 BTC in its portfolio.

Now it’s widely believed that Satoshi Nakamoto mined 1 million BTC, and with 924,768.09 BTC already in the funds, they’re closing in on this legendary figure. Since Jan. 11, Grayscale’s GBTC shed around 400,000 BTC. Subtracting that from the total leaves 524,768.09 BTC.

If these funds traded every day (which they don’t) over the eight-month span, they’ve been accumulating at a rate of 65,596.01 BTC per month, or 2,154.60 BTC daily. At this pace, the 1 million BTC milestone could be hit in just over a month—roughly 34.8 days. Even with potential fluctuations in the trading pace and inflows or outflows, there’s still a strong chance they’ll cross that threshold sometime in 2024.
