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.
As you know, this is the best way to preserve secrecy and lose track. It can be used for legal or illegal business, but being used for illegal business does not mean that it is useless. Actually, it is our right to protect our privacy, and why not use it? Mixers are not the reason for illegal business, they just provide the service, how you use it depends on yourself.
