Bitcoin, the first, biggest and most important cryptocurrency blockchain is a often referred to a "public ledger". There is no obfuscation built into itz all transactions you make are public and if someone knows your wallet address they can see every transaction you've made. Very few cryptocurrencies are private by default (eg, Monero) and they hold a very small portion of the cryptocurrencies market cap.
