I'd ask him about his identity and convince him that I'll keep it top secret and won't tell anyone that he she they is are Satoshi.jk
I'm not interested in knowing about the identity of Satoshi, but exactly as big_daddy said, I'd just thank Satoshi for all the great work he did for the community (and maybe he's still doing it behind the scenes).

I will appreciate him first for such epic idea and innovation of bitcoin.
I'll suggest to him that the whitepaper need to be reviewed in order to capture and handle some other financial issues not currently there.

If that happens I will thank him for creating a virtual currency/cryptocurrency that makes it easy for people to pay. And also because of that everything I want can be realized because of bitcoin, maybe that's all because I'm not interested in knowing his identity further so let satoshi remain anonymous .

If I meet the real satoshi, I will thank him, because, with the creation of bitcoin, my life has changed for the better.

But, I'm not sure that the person who uses a bitcoin twitter account is a real satoshi. Even though I have no proof, but I'm very unsure.

There are many variables here. Do we know for sure it's Satoshi or it's a person simply claiming to be Satoshi? Is Satoshi's identity publicly known by that time? What is the purpose of Satoshi contacting me? But if we set all this aside, assuming that the identity is unknown but I somehow know for sure it's Satoshi when I receive that message, I would thank this person for such an invention, perhaps tell how it changed my life and also say I support Satoshi's intention to stay anonymous and thus won't ask for details and won't share what I already know publicly.

I would ask him when I should finally withdraw?

It'll be just a simple conversation. I just want to say hello to him and ask him what took you you so long to show yourself. wanna thank him for everything he did, he made something that made the world government changed their perspective about money and finally I will tell him to give us some more enlightenment about what else can bitcoin does.

He doesnt need the community, in fact the community needs him. Also If I were him , I would not want to associate myself with bunch of stranger that consider me as their 'god' . Atleast Thats not my taste though

Receiving "hello" from a real Satoshi will be really great feeling but I think it would not happen on me because I am just a simple man or simple miner in the cryptoworld, but if this thing happens I would thank him for everything he had done for the community and I will congratulate him for making bitcoin success and well known all over the world. I will tell how great I am now because of what he had made, it really helps me for what I have now.

Having a conversation with Satoshi is really a good thing because you are talking to the person who made the bitcoin.

I think asking that kind of person is really personal for him,  I dont think that he will answer that question.

Giving him gratitude is enough for everthing he had done for the community. Yes for sure he is really busy doing some stuffs.
