I have not heard of this part about why Satoshi Nakamoto disappeared from the face of the earth unnoticed. This could be true but I don’t think so either. The decentralised nature of bitcoin will be at cost if Satoshi Nakamoto will still be known today. Many people think his disappearance was the best for bitcoin to thrive till today. With the way bitcoin has moved from inception till now, if he never went offline and left an untraceable clue to himself, he would have been clamped down by now and this technology will not survive till today. Satoshi Nakamoto still remain unknown and that is amongst what is making this technology to maintain its decentralised nature and still alive today. In as much as I want to know the face behind this great technology, if it will cost bitcoin to stop existing or expanding, I would wish to now know him and he should remain anonymous forever.
