Just putting this out here for people trading with the OP: There are a lot of telegram accounts that will contact you pretending to be a OP. Please do not send any money without confirming the telegram id ownership from OP. I got contacted by someone claiming to be them and when asked for a message from their the forum account, they blocked me. I'd say, don't deal with anyone from telegram at all unless you know the person very well.
You are right.
Please note: If want to trade with me for the first time then never trade with me base on telegram discussion. For Btc I will post my BTC wallet ID on bitcointalk and for skrill/paypal/payoneer I will send an email over bitcointalk message. There are a lots of scammer on telegram who may use the same name as well as an image of mine and also almost the same telegram ID of mine. For example, see this scammer, scammer. And keep in mind that I will never send a message first to discuss trade. If someone wants to trade who pretends me on telegram then that person is a scammer. So, avoid that person at any cost. To confirm my telegram username please check on my profile.
