Everybody will have access to all of your transaction because the blockchain is open source to public
First they'll have to figure out which addresses are mine.
Then they'll have to figure out who owns the addresses that I send bitcoins to.
That won't be very easy to do.
You will need to be paid by your employer with your address , right? .Very easily done!
Sorry, I use a new address for EVERY TRANSACTION. It is a simple step that everyone should take.
As such, the employer will know the list of addresses where they sent my pay, but they won't know any of my other addresses.
Furthermore, I can forward those bitcoins I receive from my employer to a random list of new addresses that I create sending a random amount of bitcoins to each address. As such, the employer won't know which of those outputs are to addresses that I own, and which are payments to someone else whose addresses my employer doesn't know.
From there, I can choose to only do business with entities that use a new address for every transaction. As such, the employer won't know what I am buying, because they won't know who owns the addresses that I am paying.
Here is an address that I received a bitcoin payment at recently (1AtcerBxCDe3KUWR2HoFJ1BRcJHMARt5Hv). Please estimate for me the total number of bitcoins that I am currently holding. Additionally please tell me the owner of any address that I have ever sent bitcoins to based only on knowing this bitcoin address (no cheating and searching the forum for someone that I've publicly stated that I purchased from or sold to).
Employers will know everything you buy , and start judging you, based on your life style
No, they won't. But if you are careless, they might do that to you.
