Privacy-o-meter for Bitcoin Transactions

Privacy score result
for the transaction:

Matched addresses identified

Using several indicators we were able to link the similar types of addresses involved in this transaction. We identified which of the recipient addresses possibly belong to one or more senders. Such matching significantly reduces the anonymity of addresses.
Matched inputs & outputs
1,037.42000000  BTC 4,979.62 USD
1,037.41892470  BTC 31,027,126.00  USD
0.00100000  BTC 29.91  USD

Issues that are possible to fix

Round value
If one of the outputs has a round value (like exactly 1 BTC) — this output can be considered as the recipient
How to improve?
Next time don't send round values: instead of sending 0.1 BTC, send for example 0.10124.
Output value x1000
One of the two outputs is 1000 times bigger than the other meaning that it's potentially the change output
How to improve?
Next time, try to use the address where you hold a smaller amount of BTC to avoid recognizing your change address among recipients.

Software-dependent issues that are not fixable

Discrepancy: no output of the same type as inputs
The sender probably uses software generating the same change address type as the recipient address has.
We use 100+ indicators to measure the privacy scores of Bitcoin transactions.

In some cases the score may be improved, while some indicators are dependent on the software used to interact with the Bitcoin blockchain. Such privacy issues are not possible to fix unless the user changes the app or website used.
Critical - The identified issues are significantly endangering the privacy of the parties involved. Usually, the critical score is shown when it is possible to group the addresses that belong to the same owner or when the transaction has a lot of privacy issues.

Low - The identified issues are severely jeopardizing the privacy of the parties involved. Usually the Low score is assigned to the transactions with a lot of privacy issues.

Moderate - The identified issues are not that severe but can still be used by tracking tools to trace your transactions.

High - The identified issues are negligible and do not pose a serious threat to the privacy of involved parties/addresses.

Healthy - The transaction has no privacy issues. Third parties can’t extract any privacy-related information about the transaction or addresses involved.

General guidelines for sending BTC transactions

Blockchair can not help you improve the privacy of your
transactions but here are some basic recommendations
on how to stay anonymous on the Bitcoin network
Don't send round numbers

Don't send round amounts. Instead of sending 0.1 BTC, send 0.10125

Use Bitcoin Mixers

Mixers add an additional layer of privacy to a transaction to avoid exposing user identities.

Avoid reusing wallets

Don't send your Bitcoin change to the same address you use for sending bitcoins.

Avoid including many of your addresses in one transaction

Any time you can, try not to send BTC from your various Bitcoin addresses.

Avoid using "send everything" option

If you are withdrawing funds from an exchange, it is okay.
If you're moving funds to another wallet, do not transfer the whole amount to another address. It greatly compromises your privacy.
