As long as it DMs you, with a complete full name and no bio or everything on TG, it’s 100% bot or prolly just want to take advantage you. Big fish dont dms, if they dm you in crypto means they want something from you. Scammers are everywhere in crypto, and these aren’t the only script they use but the tip is, if they want something or offer a negotiation, it’s 100% scam. Don’t fall for these kind of scammer strategies, if you are a newbie expect that experienced people will not spend time to you.
That's how I was on my own and I received a message from one person. Only knows where he got my contact but I'm very positive he got my contract from a group chat, he can't convince me otherwise because my telegram is an old account, I had lot of groups and channels that are full of spammers and inactive teams. I don't know the scammer intentions but if he is not after something, he wouldn't have message me trying to convince me if I'm interested in Temu sales and all that, told him to stop there that I wasn't interested in anything he has.
OP is right, don't entertain what you are not going to accept, the more you allow a long conversation from a stranger, the more they try to win you with some words, before you know it they will paste you a link that has some script that can destroy your phone and computer and then probably take something from you. How strange telegram can be, I have real contact of people I know in that telegram and I never for once see their dm, it's always the people I don't know.
