It is almost always a question of the intention of fraud. The conversation usually starts with a short introduction, an inquiry about personal life and, if possible, giving a certain dose of empathy. It's actually a psychological game and it's trying to gain some kind of trust.
Everything is actually preparation for what follows, proposing a very profitable investment, business or whatever. Because you will more easily accept and believe in advice from someone you already know in some way. if you are a little more inert, it will be harder for you to tell him to screw up, and he will use that to pressure you to give in and believe his proposals.

If, for example, you would slow down the conversation or answer only briefly, the business proposal would arrive quite quickly, without further intimation. still want to try because you are responsive and didn't block him immediately.

Always keep in mind why a complete stranger would contact you and propose a super profitable job or investment. That doesn't even happen in fairy tales, there is always a final motive.
If such things bother you, right-click on the username and the "block" option is the solution. You should not allow any harassment from unknown people on the Internet

I am fully secure in my view. I remember a person that chatted with me after I joined a telegram group, telling me that he is from Brazil and introduced me to meta trade or something. I laughed and start to take his time too. Where it landed is a lie from me to have a physical visit with me in my country. It ended as nothing, no scam success because I knew he was a scammer even before the start of our conversation. Nothing like online friends to me, they are all scammers and they have not disappointed me before not to be a good person. Recently I got busier and I just ignor strangers. I did not also join groups again and nothing like new stranger 's messaging.

Just as have said earlier, I have never involved myself with any online services or in dishing out my contact information to anyone else to contact me, as a matter of fact I was very surprised seeing such activity.

Perhaps the user is feeling lonely in a new country and needs a local as a penpal.

Jokes aside, could he have located you by searching your Telegram handle which might be the same as your username here?

There is no security risk at the point of you receiving an unsolicited PM, i don't think there's any user who hasn't received such before, what matters is how you handle it or if you have the already existing knowledge about the modus operandi of scammers. I discovered that Bitcointalk forum users know how to detect and evade scam pretty easily because of the knowledge we garner here, but you'd be surprised at the number of people who fall for all this, or who don't know that if something is too good to be true, then it's prolly a scam.

Having said that, as long as you don't click random links from strangers, send them money, invest in whatever they offer or even continue a conversation with them, then you can't be scammed.

My answer to him was based on his questions so I was wanting to know his motives if he noticed I told him I am from his country. But No! I am not his country because I wasn't secure enough to tell him my location that's was why I responded him that way.

When its someone who knows you like a friend online or personally knows you, they will immediately say something for the conversation to start and not just saying Hi hello.

Ignore them and that''s how to secure yourself. If you see someone just saying Hi and hello, that is someone who wants to waste time. A person who has a purpose of chatting you will immediately pitch what they are offering and then you can immediately say no. End of story.

I'm not sure why you'd try to take the time to reply to few messages with someone you suspect might be. If I were you, I would block that user from the first message, no matter how pretty they look.

Then one other question, What does this thread have to do with reputation, does the user you spoke to on telegram have an account on bitcointalk and is trying to scam you or something? If this thread make for warning for attempted fraud unrelated to bitcointalk, then I hope you can move it to Begginers and Help or to the appropriate board.

it doesn't really look like its a scammer but if he waste his time with the chatter, he will find out whats its is up to.

seem nothing to worry. OP gives so much worries to this when he can just stop replying to that chat and even block the user. a girl named Sai looks beauty anyone would agree to that. unless OP is waiting for the intimate conversation and probably a phone sex after it, i can understand he wants to chat as well.
