Yes, your Bitcoin transaction history is public and can be seen by anyone on the blockchain. This means that the information about all transactions made on the network is freely accessible from anywhere across the globe. The transactions can be tracked through the use of a blockchain explorer which allows you to view all of the blocks on the blockchain and see the addresses and transactions related to them. While Bitcoin transactions are pseudonymous, they can still be traced back to the user through the use of a Bitcoin taint analysis which tracks the flow of funds from one address to another. Therefore, it is important to understand that Bitcoin transactions are not completely anonymous and can be traced if necessary.
