In the United States bitcoin has become collateral the derivatives exchanges accept

On 9 December 2025 Ether closed at $3,318, +6.2% against the previous day, and Bitcoin at $92,679.

What changes, in practice

Before the opening, anyone wanting to trade regulated derivatives had to sell their crypto and deposit dollars or government bonds as collateral, losing the exposure to the asset. Afterwards, they can deposit bitcoin, ether or a compliant digital dollar directly and stay exposed to the asset while they trade.

The form is cautious and that has to be said: it is a pilot program, the first 3 months admit only those three, whoever joins sends a weekly report detailing what they hold on clients’ behalf and has to flag any incident immediately. Alongside it, the 2020 circular that in practice stopped digital currencies being held in segregated accounts has been withdrawn, now described as “superseded”.

The part that cuts the enthusiasm down to size is that the unregulated platforms have been doing this since 2017. So it isn’t an invention: it is the moment a practice that already existed moves inside the perimeter of the rules — which is less exciting and much more important, because that is where the money that has to answer to somebody sits.

And the fund that puts it to work

Putting it to work, here, means depositing the ether as security for the running of the network and collecting the reward the network pays whoever does that. It is a real yield and not an accounting trick: it comes out of work somebody has to carry out for the network to stand up.

The point that changes the meaning of the thing is who carries it out. The manager will not run its own validators: it will delegate to third-party operators picked for reliability and continuity of service, with a principal custodian and a backup bank. So whoever buys shares is buying a yield produced by a chain of delegations of which they can see no link.

How concentrated that chain already is

A listed fund that delegates in turn neither removes nor adds decentralization: it adds a floor. Whoever buys the shares delegates to the manager, the manager delegates to the operators, the operators use somebody else’s infrastructure. Every step is reasonable taken on its own, and the overall result is that work which ought to be spread out concentrates where it costs least to do.

That doesn’t make the product wrong, and it isn’t an alarm: it is the price of making a thing convenient. It is worth knowing beforehand rather than afterwards, though, because the reason that network is worth anything is that nobody controls it — and every layer of delegation is a piece of that promise handed to somebody else to manage.

What was celebrated, and the price

That same day the company that has made accumulation its trade bought another 10,624 at an average of $90,615, reaching 660,624 in the holding. It is the day’s note of color, but it also says how ordinary this has become: a billion dollars spent in a week is no longer front-page news.

And the price, for once, moved: ether closed at $3,318 against $3,124, +6.2%; bitcoin at $92,679 against $90,634. On almost every day like this we write that the plumbing doesn’t touch the chart — here it did, and the reason is simple: collateral being accepted isn’t an announcement about the future, it is something that changes what you can do the next day.

Put bluntly: for fifteen years the motto was “be your own bank”, and the most celebrated day is the one on which an agency in Washington gave permission.
