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.
I'd suggest you do some research beforehand. Not all mixing is done to mask "questionable" transactions.
For instance, whales who wish to protect their own privacy may choose to use such mixer services. Or, people may be concerned that coins that they receive is tainted previously by someone completely unrelated to them. Mixing increases privacy, and thus increases the fungibility of BTC as a currency.
You could also try Dash/XMR/ZEC where they are anonymity centric, although the hype for these coins have died down drastically.
