Keeping records of your crypto transfers
What to save and why, in a system where the ledger is public but your own bookkeeping is not.
Blockchains record transactions permanently, which makes people assume record-keeping is handled. It is not. The chain knows that an address sent an amount; it does not know it was you, why, or what it was worth at the time.
What to save for each transfer
The transaction ID. This is the anchor for everything else and the one thing that resolves a dispute.
The date and time, the asset and network, and the amount in crypto.
The value in your own currency at the time. This is the field people skip and the one that is hardest to reconstruct later, because prices move.
What it was for, and which account or service was on the other side.
Why it is worth the five minutes
Disputes. A deposit that goes missing is resolved in minutes with a transaction ID and unresolvable without one.
Tax, in most countries. Rules differ and this is not tax advice, but almost every regime that taxes crypto needs the acquisition value and the disposal value, and reconstructing those years later from an explorer is miserable work.
Your own clarity. People routinely lose track of which service holds what, especially across several wallets and exchanges.
A simple habit
A spreadsheet is enough. One row per transfer, the fields above, filled in when you make the transfer rather than later.
Export what your providers offer periodically, and do not rely on being able to later. Services change, close and lose history.
BYCRYPTO's History shows every deposit, transfer and adjustment on your account with its reference, which covers the BYCRYPTO side. The other side of each transfer is yours to record.
