Don’t keep all you crypto assets in a single address –
Don’t share the same address to multiple person – Private keys are used to generate the Bitcoin Address. For each transaction create a new address. This way you avoid anybody to know how much bitcoin has been sent to that address in total. Generating new address everytime also protects your privacy.
Block explorer privacy – Block explorer is a web appplication that operates as a Bitcoin search engine. You can search by Bitcoin addresse, transaction hash, block number and block hash. Using these applications and searching a transaction allows them to associate the IP address, previous earches and browser details through which can identify and learn your activities. Searching somebody else transaction should not be a problem but if you search your own transactions these operators might be able to analyse the Bitcoin your have received and spent or currently own. So as mentioned earleir each transaction should be on different address to make the operators difficult to identify you.
