Let's assume that some BTC wallet has following transaction history:<p>2015: received 3 BTC<p>2016: received 1 BTC<p>2017: received 1 BTC<p>2018: sent 1 BTC<p>2019: received 2 BTC<p>In this case the number is 7 BTC<p>Do you know any online service which can do such sort of calculations?
Step 1, go here <a href="https://www.blockchain.com/explorer" rel="nofollow">https://www.blockchain.com/explorer</a><p>Step 2, in search type in the address you want to check transaction history for. In this example I typed in "Bitcoin Address" in google and copy/pasted the first one I found. 1F1tAaz5x1HUXrCNLbtMDqcw6o5GNn4xqX<p>Step 3, Click on BTC address (unless you want to check the BCH) and you will get <a href="https://www.blockchain.com/btc/address/1F1tAaz5x1HUXrCNLbtMDqcw6o5GNn4xqX" rel="nofollow">https://www.blockchain.com/btc/address/1F1tAaz5x1HUXrCNLbtMD...</a><p>Now if someone has a wallet and is constantly changing addresses with each transaction, that is something that I am unfamiliar with as I don't buy/hide stuff online with BTC.
