1 million bitcoins is bit much now. estimated value of that is 5 billion$ just for holding the bitcoin.. what if satoshi nakamoto invest in ethereum and all the top 10 alternative coins today. 
do you think bitcoin will be monopolize as well in the near future just like all banks that control by rosthchild?
I think that he wouldn't even be able to sell all of his bitcoins on any exchange that easily. I mean, there is no suffiecient demand for 1 million bitcoins just like that. Maybe that's why we don't hear about it. He keeps it for the future, when everyone will be using bitcoins or when all of them will be mined, so that there is his last supply to the community. do you think bitcoin will be monopolize as well in the near future just like all banks that control by rosthchild?you have a point.. but on this day you buy plenty of things using bitcoin. many countries now accept bitcoins for buying real estates .. so maybe even there is no sufficient demand for 1 million bitcoins. he can use few bitcoins of him to buy real estates or things that he need
because i myself keep bitcoin and use a little bit as a reward for myself
