lets assume that satoshi has that huge bag of coins. lets also assume that he/she (they?) is still alive and has still access to the private keys.
why hasnt he/she spend or even moved those coins? any speculation?
Since he is the creator of bitcoin he knew or can predict the price of it so he could be waiting for the bitcoin halving and will move his coin once the price skyrocket,this is my opinion..
its possible to happen?satoshi as bitcoin creator would do something that will never predicted by everyone?i dont think so.
but if more people believe this is ready to bitcoin halving,so i will spent my bitcoin and trade to cash money before satoshi move my bitcoin,, LOL
