I don't want to call it as "weird" but more on "random" types of messages because... they really are just random DMs from random strangers.

Anyway, I've received the same types of messages on a monthly basis, and it's not only related to crypto trading. There are also times where they're saying that they're giving some kind of work where the task is very easy, but they'll be paying you very high and for most of time, unrealistic. More like a "work scam" or I don't know the exact name of that one, but they'll require you to deposit money in order to withdraw the money that you earned thru working which will just end up as a scam.

Telegram is a den for scammers, same with Discord so the 2 things that you can do is to just ignore, or block them... or maybe there's a third one, and that's entertain them, but don't fall into their scam trick. Just to entertain yourself maybe if you're bored. Newbies here, please beware of these random strangers DM'ing you out of nowhere, and always think, if it's too good to be true then it's not true.

I’ve been receiving a lot of those messages too. Sometimes they pretend to be a dev right after you join an official channel. But the funniest part is when you get a DM from a real dev because of those 'rank your holding' bots. If they see you are a whale or a shark, they might message you just to try and stop you from selling or to boast about how good the project is.
It’s kind of annoying how they watch everyone's bags like that. It makes me want to stay quiet and not use those bots at all.

Here's how it works:

The bot networks hang out behind real Telegram accounts that are linked to channels of various crypto projects, for example. The more open the channels are, the easier it is.

The real Telegram accounts are then used to read user data and listen for messages such as "support". These people are then automatically contacted and/or the lists of accounts are collected and sold on the darknet.

You can try this out for yourself very easily. Just join a crypto project's Telegram channel and write "I need support." In no time at all, you will receive a lot of DMs pretending to be support from crypto project XYZ and offering to help you (or scam you). However, these users are not actually in the channel themselves, but receive this information via the main account.

been also receiving messages from unknown people, the best solution is to blocked them immediately, no need to be curious because if you make a mistake like clicking a link accidentally or being curious that would result to something big in the future.
They are not popping they are already there they are just looking for a possible target or victim the moment you interact that would even go beyond, and I'm afraid some people really fall for it, and they also invited or join by their families and they are all been scammed in the end, so if someone you did not know message you about something, or saying he is this and that, blocked it automatically.

Only the newbies and greedy people are the ones that will fall for this scam, I received many messages in telegram and I have never for once reply them because I know it is all a scam, they are doing all this to get the attention of those greedy people who are eager to make it by force, when you are someone who is holding bitcoin or you invest in a coin, you have to be careful and be smart because they can use anything to make sure they get your attention.

Telegram has become a very dangerous place because that is where scammers see as a good place to get the attention of people, i don’t reply anyone on telegram because of the scammers who have make the place look somehow for people, it is still a place to communicate but we should be careful and not reply anyone who send us link or any unnecessary messages.

Telegram is indeed the most convenient place for fraudsters to find victims, especially beginners with a greedy mentality. This makes it very easy for fraudsters to carry out their operations. Telegram users, especially those involved in crypto, are unavoidable. You'll receive these strange, tempting messages almost daily. Therefore, whenever you receive a message, you should ignore it and, if necessary, block the user.

This is Telegram's weakness: it can't automatically filter fraudulent accounts. Scammers can even easily impersonate project developers and so on which can lead you to believe the message. This is also why there are so many threads on this forum discussing scams, as the crypto world is a prime target for scammers especially if you're a greedy and careless beginner.

Actually, this is an old method that scammers have been using, I believe they can do better that that user, might be that this particular scammer that chatted you on telegram is just new in the game. However, the best thing to do is clicking the block button asap. There's no point in trying to figure out their moves. At the process of listening to them or lets just say replying to their messages they might send you some phishing links and if you lock on them, they can hack into your system remotely.
Moreover, I haven't received any suspicious messages on my telegram lately. Besides I am not always active on telegram, I only check the Bitcointalk notifier bot.. that's all. So I think I'm safe here.

Not sure how much it costs to obtain a Telegram account, but I bet it's low enough that they can continue spamming messages like that everywhere. There's no way they'd do that if the cost is high. It's not that hard to imagine that out of 10k targets, only 10 or 100 fall for scams, yet the money they got probably covers all their bills. Some of them are probably forced if those true crime stories are to be believed, but the chance is low. They might use bot too.

Yeah, that's the easiest and most peaceful way to deal with that.

That which you think will be unnecessary for them is the one they will go for. Getting premium accounts will even make users suspect them less. Scammers are calculative. They don't mind spending cash once they're convinced it will yield them a lot. It's like getting a blue tick on certain social media apps which make others trust that such users are verified as genuine. But of course, we've found several times where those verified accounts scammed people and disappeared.
