Bitcoin is pseudonymous not anonymous which means all bitcoin transactions are visible on the blockchain network. Monero on the other hand is a privacy coin and its transaction are not public. If you’re trying to hide your transactions or paranoid about privacy, coins like Monero and Dash are the coins for you.
About DASH, there is a funny history about their team denial to be a Privacy coin. For years, they claimed to be a Privacy coin but when there were attempts to break down Privacy coins, delist these coins on Centralized Exchanges, DASH team turned around and said their coin is not a Privacy coin.
This funny action from DASH team happened four years ago.
