Large-Value Transfers

The chain records transactions that moved very large amounts of bitcoin. A large transfer is a movement between addresses, and reading it as a sale is an inference the record does not support on its own.

Fact

The chain records the amount and the addresses of a transfer, and the block that confirmed it.

Forecast

Whether a transfer was a sale, a custody move or an internal shuffle is not recorded and is not asserted.

What the record shows

A transaction names the outputs it spends and the outputs it creates, and it carries an amount for each. When a very large amount moves, the chain records the amount, the addresses involved and the block that confirmed it. Those are the facts the record holds.

What the record does not hold is any statement of purpose. A transaction has no field for the reason it was made, no field for who controls either address, and no field for whether the coins were sold, moved between wallets, or sent to an exchange. Those are inferences drawn from the addresses, and they are only as good as the attribution behind them.

A transfer to an address known to belong to an exchange is often read as a deposit and therefore as a potential sale. The inference is reasonable but not certain: the same address may serve many purposes, and a deposit may be a custody move rather than a trade. This page reports the transfer and labels the reading as an inference.

Timeline

2011 onwardsThe chain records transfers of increasing size as the supply and the market grow.
RecurringVery large transfers are reported, often with an inference about their purpose attached.
OngoingThe record continues to show amounts and addresses, and continues to omit any statement of intent.

What the record does not settle

The gap between a transfer and a sale is the gap between what the chain records and what a reader wants to know. This page keeps the two separate: the amount and the addresses are facts, and the purpose is an inference that should be labelled as one.

The exchange flows page covers how deposits and withdrawals are estimated, and the limits of blockchain analysis page explains where attribution stops being reliable.
