It is possible, that Satoshi is/are reading all these bitcointalk contributions ... and although some pepole want him/her/them to come back, nothing happened.
Tell one good reason why Satoshi should come back. (good reason = improvement of Bitcoin)
Personally I don’t really see the need for having Satoshi Nakamoto back. If he should come back, there’s likely going to be a change in the price of Bitcoin, and is more likely to be a decline. Why I am saying that it is more likely going to be a decline in the price of Bitcoin is because, they hold the largest amount of the coin, and if they should intend to withdraw it whenever they show up or take anything out from that amount that is in that address, it is going to affect the market heavily and it will drop.
This will in turn affect other crypto currencies (altcoins) in the market, such as ethereum, and others that their prices correlates with Bitcoin. Bitcoin has kept progressing whether there is Satoshi Nakamoto or not, so why do we even need them now? If he or they decides to stay out of the picture, then we should let him be.
