Please I may not be the only lame man here I've longing to know why People typically use bitcoin mixers to mask any previous "questionable" transactions from the bitcoin that they are likely cashing out in their real name. Now let me know about purpose of mixing bitcoins.
OK if you don't mix your coins, you can easily be tracked because of blockchain (which is public), so your privacy is somewhat breached, which is one of the main reasons why people wanted to be in crypto sphere in the first place, hide their wealth.
So if you used mixing services, you somewhat obfuscate your identify and improved your anonymity.
