Of course he is real.  He is the person behind the bitcoin and cryptocurrency we are being benefited right now.  He is the person behind blockchain.  His idea might impossible when he first introduce it in the market way back 2007. But, people start to recognize, trust and put confidence on it as the time goes by.  He only leave the bitcoin scene on the year 2017.  Some speculation says that he leaves the bitcoin world because other data center intended to bitcoin mining begin to sprout where some countries manipulated it (which is far from his aim of decentralization).  This is the reason why some people says that Satoshi Nakamoto is not real.

Even Satoshi Nakamoto's original plan does not all happen (such as no transaction fee), Still, his idea about bitcoin is helping billion of people around the world. And, here we are now, thankful for his wonderful idea about cryptocurrencies because it give as a great platform to earn money.  I am also confident that bitcoin is on its way to hit its aim in having one world currency.  Bitcoin is the future of money.
