Trading on Telegram is not an easy one because of lack of trust. Very few of the trade has come through for those who manage to the risk.  So many people have fall victim of been scammed. I have done a few of them using www.freelancer.com as an intermediary between me and the person. Freelancer is a well known and trusted site where workers and employers meet to arrange for work or task and payment so that there will not be a bridge of agreement at the end of the day. It allows both of you to open an account, the employer will transfer its money to the site for payment of task done after due assessment of the work. If there is any bridge of agreement you can raise a dispute for the site to release your money to you.
