I Needed 212 Rows of Records From an Exchange That Died in 2023

On a Saturday morning in June, at 9:20 with coffee going cold next to the keyboard, my accountant said eleven words that ruined my weekend: I need the full history, not the summary, the rows. Two hundred and twelve rows of it, from an exchange that announced its shutdown in the fall of 2023, processed its last withdrawal that December, and left behind a website that still loads but serves mostly ghosts. My capital gains tax calculation for three messy years was gonna be built from whatev I could dig outta a company that no longer exists. The stakes were exact, not vague. Without the row-level data, my accountant would hafta treat certain disposals with worst-case assumptions, and she estimated the inflated bill at approximately $1,900 more than the true number. That is a real amount of money to pay for missing a spreadsheet, and it was sitting on the table because I had trusted a platform to exist forever.

the site that still loads and answers nothing

The old domain resolved, the login worked, and the portfolio page showed my ancient balances down to four decimal places, which felt like visiting a preserved living room in a museum. But the export function had been dead since the wind-down, returning a spinner and then nothing. The help center linked to a support email that bounced. Page two of their wind-down FAQ, in a bullet nobody was meant to need, named a third-party records custodian with its own request portal, and that single bullet became my whole project for a month.

four weeks of archaeology

Week one: the custodian's portal rejected my request because the ID format I submitted matched their old system, not the migrated one. Week two: a human named Priya replied asking for proof of address from the exact quarters I had lived at my previous apartment, which required a call to my old landlord for a re-sent lease letter. Week three: silence. Week four, on a Tuesday at 4:05 PM, an email with a subject line of no reply needed and an attachment: 212 rows, spanning March 2021 to November 2023, every fill, fee, and transfer timestamped to the second.

what 212 rows actually contained

Opening the file was peculiar, like reading my own diary written by a machine. There was the panic cluster of March 2021, nine sells in ninety minutes. There was a $4.75 fee I had complained about in a support ticket at the time and forgotten by dinner. There were pairs I had fully erased from memory, and two slight disposals I had never reported, which my accountant handled properly rather than pretending away, cuz the whole point of assembling honest capital gains tax records is that the correction goes one direction.

the cost of assuming records keep themselves

Total cash cost: $0 in fees, four weeks of latency, and about six hours of my time chasing proofs. Total risk avoided: the $1,900 padding and, worse, a filing built on estimates that would not survive a question. I now keep my own exports quarterly, on the first Saturday of each quarter, saved in three places, and my accountant gets them without asking. My brother called it paranoid. He also filed for an extension last year because his platform's export only went back twelve months.

the cross-check that caught two ghosts

Before handing the file over, I reconciled it against the one source I did have: three years of bank statements showing my own deposits. Eleven withdrawals on the statements had no matching row in the CSV, which turned out to be transfers between my own accounts that the export labeled differently than I remembered, plus two genuine gaps the custodian patched in a follow-up email. That patch took another six days and one more proof-of-identity round. Annoying, yes, but compare it to signing a filing that asserts two disposals never happened. Reconciliation is how you find out the archive is almost complete before the government finds out for you.

what I would tell the 2021 version of me

Export everything the day you make it, not the year you need it. Assume every platform has a lifespan shorter than your records retention obligation, cuz the wind-down notice for mine arrived two years after I weighed it permanent. Keep the fee columns, keep the rejected orders, keep the boring rows, because the boring rows are the ones an auditor counts. And when a shutdown announcement mentions a records custodian in a footnote, screenshot that footnote the same day.

June, closed out

The final filing went thru in July with every one of the 212 rows accounted for, and the bill came in $1,860 below the padded estimate, which is the cleanest money I never spent and the cheapest month of archaeology on record. I keep the custodian's email pinned in a folder labeled proof, next to the lease letter from my old landlord, who now thinks I am in some kinda trouble. In a way I was. The good kind, the kind you fix with paperwork and patience.
