Why Satoshi Left.
Some crypto experts believe that Satoshi simply lost interest in Bitcoin and left the project. The coding was getting too difficult, and there were some flaws in the protocol that needed to be settled. Others believe that he’s still actively involved but with another pseudonym this time. And then some others think Satoshi left because he thought Bitcoin wouldn’t progress if he stuck around.
Before Satoshi left, he made a post on Wikileaks accepting Bitcoin. This makes some people believe that Satoshi got nervous about getting attention from Wikileaks, and this is why he left.
