if what you are trying to imply is true that satoshi still has a stack of million bitcoin's.
then i believe enticing him to sell this will cause more disadvantage rather than benefits.
aside from totally disrupting the market price - other people may also lose trust with bitcoin and make them leave it for good.
.
for me it will be better if we will leave it the way it is.
if satoshi was able to hold it until this time then it only means that he can hold it for a longer time.
we don't have to be afraid of what he is hodling because i am confident that he knows what he has to do with it.
