I contacted someone going by the name of Lucas Bobby, after seeing his name mentioned in some comment under a crypto youtube video. People there were suggesting he had helped them increase their bitcoin through trading. In hindsight, I suspect those comments are all placed by the same Lucas Bobby, using several fake account to make it seem genuine. I found him on telegram. We then connected on whatsapp and he got me to set up an account on zcointrading.com and put some btc in it. He instructed me to place trades that all seemed to be winners. However, he then asked me to open another account on the same platform and I discovered that the deposit address for that second account, using a different email, was identical to the first account. So it looks like all the deposits to seeming separate accounts on that platform are in fact all going into this same wallet.
