The crypto space is for everyone, especially when it has something to do with Bitcoin. Bitcoin don't really need adverts, because with what it has shown so far and the kind of trust it has built for itself one don't need to convince anyone to invest in to Bitcoin. However if you start convincing people to use Bitcoin it will look like a scam because that's what scammers actually does, they convince people to invest and they take their money from them.
Satoshi Nakamoto knows why the future of Bitcoin will become that's why he didn't try to convince anybody. Trying to convince people about Bitcoin might even reveal his identity.
Yes you are right, you don't have to convince anyone to invest in Bitcoin. Because Bitcoin is so popular that no one needs to be recommended to invest in it. I agree with you that if you convince someone, it will look like the behavior of scammers. It is better not to try to convince anyone about Bitcoin. Because Bitcoin's position is very advanced. If you try to convince someone about it, they will take it lightly. So maybe he didn't try to convince people about Bitcoin.
You're right Bitcoin has become a global asset that is even treated as a security asset in most countries who are for sighted enough to recognize Bitcoin so trying to convince someone to be investing in Bitcoin is like forcing someone to eat food when the person is not ready anyone who is not ready despite all in needed information out there including the net and on platform like this is needs no persuasions to invest in because forcing someone to invest in Bitcoin when the person is not yet ready may not end well because they person not fully understand the potentials that Bitcoin has and how it has really lifted plenty people above the poverty line
