So basically if you read what he wrote the concern is that if they publish the whitepaper before development is further along other coins will attempt to beat them to market. This whole OMG you must publish a white paper BS is driving me nuts half you trolls dont even read it let alone understand it you just want to see it.  As we have already seen in the last month XST has been a target for copy cats some just taking code base and adding to it some just blatantly ripping it of website and all. The last thing that XST needs is to prematurely reveal how they are making stealthsend and have one of the copy cats beat them to market with it. Most companies try at all cost to avoid  competition and keep big plays like the game changer stealthsend is going to be very close to the vest. I personally applaud the teams effort to protect my investment and i am waiting patiently.
