Last quarter we shipped the first transparent, size-based rate table in crypto lending. Today we go further. Arch is dropping rates platform-wide and simplifying the size-tier structure for our clients. We now have the lowest qualified custodian rates in our industry!

Bitcoin’s supply grows about 4.5% from here, and then it stops. Gold and dollars keep compounding. We ran all three forward 50, 100, and 150 years at today’s growth rates.

These are projections at today’s rates, so the assumptions matter. Gold reaches 9.1x only if mine output keeps growing with the stock. At a flat 3,300 tonnes a year, it’s 3.2x. M2’s yearly growth has ranged from below zero to above 25%. 6.7% is the 67-year average.

A fixed supply doesn’t tell you what Bitcoin’s price will do next year. It does fix the coin count: 21 million. Holders who need dollars can borrow against their Bitcoin at Arch instead of selling. Bitcoin is volatile: if its price falls, your LTV rises.

In 2017, Jamie Dimon called Bitcoin “a fraud.” It traded at $4,131 that day. On Oct 19, J.P. Morgan Asset Management published its first long-term Bitcoin forecast: 10% a year over the next 10-15 years. That’s above its forecasts for U.S. stocks, private equity and gold. Here is the record, with Bitcoin’s price on each day: Nov 2015: “That’s going to be stopped.” $412 Sep 2017: “It’s a fraud.” $4,131 Jun 2018: “Just beware.” $7,678 Oct 2021: “I personally think that Bitcoin is worthless.” $57,485 Sep 2022: “They are decentralized Ponzi schemes.” $18,547 Jan 2023: “Bitcoin itself is a hyped-up fraud, a pet rock.” $21,087 Dec 2023: “If I was the government, I’d close it down.” $43,746 Jan 2024: “I call it the pet rock.” $42,743 Jan 2025: “Bitcoin itself has no intrinsic value.” $94,488 May 2025: “I defend your right to buy bitcoin.” $105,606 The shift started in 2025. In May, JPMorgan said it would let clients buy Bitcoin. In October, Bloomberg reported it would accept Bitcoin as loan collateral for institutional clients. Then the forecast. JPMorgan’s 2027 Long-Term Capital Market Assumptions put Bitcoin’s base case at 10% a year. Private equity: 9.8% U.S. large-cap stocks: 7.5% Gold: 5.5% None of this says what Bitcoin does next year. It does show how far the conversation has moved inside JPMorgan in nine years. Arch lends against Bitcoin, so holders can get dollars without selling. If you want to see what that looks like for your position, our team can walk you through it.
First they ignore you, then they laugh at you, then they fight at you, then they add you to their Long-Term Capital Markets Assumptions paper and predict you'll be the best-performing asset of the next decade.

Boring markets are where good plans get made. Nobody plans well in a panic.

Remember: Bitcoin sold is Bitcoin gone. You can read that again.

We took $100K a year out of 10 BTC in three different ways and followed each plan for 30 years. The starting price is $83,500, and BTC grows 15% a year. Here is the breakdown 🧵

7/ The number to watch is LTV. It starts near 12%, peaks at about 54% in year 11, and then falls every year as the price growth outruns the interest. It is 44% at year 20 and 30% at year 30.

8/ Same $100K a year, three endings: - Out of money in year 8, - Last sat gone in year 20, or - $38.8M at year 30 with a loan to manage. The borrow plan depends on the stack outrunning the cost of the debt. Illustrative only. None of this is financial advice, seriously.

In The Bitcoin Standard, @saifedean gives one test for what can hold value and work as money: salability. Here's what it means and why only one asset alive today passes all of it. 🧵

Salable across scale: the asset divides and combines to fit any trade, big or small. If you can't sell a piece of it without destroying its value, you're stuck selling the whole thing or nothing. Gold = small bars trade at a worse price. Land = you can't sell the doorway of your house. Stocks = splits are corporate decisions. Bitcoin = every coin divides into 100M sats.

Every monetary asset before Bitcoin traded one dimension off against the others. Gold chose time and gave up space. Fiat chose space and gave up time. Bitcoin is the first one that didn't have to choose. (Chart attached. Not financial advice.)
