A balance left behind
Rank one, and there is nobody on the other end of it. That combination is why it stays at the top and why almost nothing written about this subject mentions it.

What a parked balance actually is
Money handed to a platform and not committed to anything. It is not in escrow, because escrow governs orders. It is not covered by the signing arrangement, because nothing has been contracted. It is held on your behalf by a party you cannot identify and have no recourse against.
Every protection described anywhere on this site attaches to an order. A balance has no order attached, which means it has nothing attached.
What actually takes it
| Event | How likely | What happens to the balance |
|---|---|---|
| You lose access to the account | Far more likely than the platform failing | Gone with the account |
| Your attention lapses | Very likely across months | Nothing, until one of the others happens |
| An extended outage | Occasional | Not a loss, and a stretch where you cannot reach your own money |
| The platform ends | Unpredictable | Gone. Every market that ended looked healthy first. |
Why people leave one
Three reasons, all understandable. Funding is the least pleasant step, so people do it once and generously. Fees make a single movement look cheaper. And a balance feels like it is somewhere rather than nowhere, which is a feeling about custody rather than a fact about it.
The fee argument, answered
It is the only real argument for leaving funds in place, so it deserves a direct answer. Each withdrawal pays a network fee measured in fractions of a cent. Leaving money there to avoid it buys convenience with an unbounded downside to save an amount too small to write down. That is not a close comparison, and it is the reason this entry sits at rank one with a prevention cost of nothing.
The test that works
Can you name the date the balance leaves. If you can, a small remainder is defensible. If the honest answer is that it stays until you next need it, the decision has already been made by inertia rather than by you. Keeping no balance is the habit that removes this entry entirely.
The custody question, stated plainly
A balance is a number in somebody else's database saying they owe you. That is true of a bank as well, and the difference is everything that surrounds it: with a bank you know who they are, where they are, and what happens if they refuse. Here you know none of those, by design, and the design is the point of the whole arrangement.
So the question is not whether the operator is honest. It is whether a claim against an unidentifiable party is an asset, and the honest answer is that it is an asset only for as long as nothing goes wrong.
Why the loss is usually invisible until it is total
Nothing warns you. A balance behaves normally right up until the moment the account is gone, the platform stops answering, or the credentials stop working, and every day it survives is read as evidence that it is safe. That is the same reasoning that makes people comfortable with reuse, and it fails the same way: absence of a bad outcome so far is not information about the odds.
A rough sense of scale
| If you hold | And the account goes | You lose |
|---|---|---|
| Nothing | Annoying | A username |
| One order's worth | Bad day | The order you were about to place |
| A month of intended spending | Expensive | A month of intended spending, permanently |
| A round number that felt tidy | The common case | Whatever tidy meant at the time |
The last row is the one that appears most often in accounts of this going wrong. People do not decide to hold a large balance. They fund a round figure because round figures feel like good practice, and the remainder simply stays.
