I'm pretty sure that @trafalgar has openly stated what he invested here:

(This is a top post to those who have not seen it!)
This investment has long been payed off and without looking, I guess his account is around 1,500,000.
The rewards have long outshone any risk for many, even if the place blows up tomorrow.
good to know this ^^^ thanks! a lot of people use that to excuse the behavior of the initial investors saying they deserve it
