This is an excerpt from the 'leaked' document. (emphasis mine)
"The reality is that MtGox can go bankrupt at any moment, and certainly deserves to as a company. However, with Bitcoin/crypto just recently gaining acceptance in the public eye, the likely damage in public perception to this class of technology could put it back 5~10 years, and cause governments to react swiftly and harshly. At the risk of appearing hyperbolic, this could be the end of Bitcoin, at least for most of the public."
How do you put back a technology 5 to 10 years that is barely 5 years old?
I guess you tend towards the lower end. Or perhaps he meant to say 5 to 10 weeks.
Also notice the phrase "this could be the end of Bitcoin". Sound familiar?
It looks more than anything like the wording was chosen specifically to create a panic.
