One of the reasons why most of us prefer to trade anonymously is because of security nowadays hackers are too aggressive that they will even steal all your personal information, and use it for their own goods especially if you are one of the whales then tons of bitcoins can be stolen to you if they can have access to your personal information and your account. Perhaps you want to know how we can trade anonymously is by your username and the rest of the transaction may no longer be 100% anonymous especially when you do exchanges like cashing your bitcoin. Indeed, --KYC's are now being imposed on any form of trading and as soon as it will be implemented in cryptocurrency then much likely we cannot do trading anonymously anymore.
