What was my action:
I quickly try and withdraw (empty the bitmex account), then I realised it got frozen and the money didn't get transfer to me. As I was doing this, I was reading this forum post then I realised if I empty it, they will suspect. I must withdraw the money in smaller chunk. Hence I went back to bitmex customer support and told them to cancel the transaction.
After they cancel it, the account was unfreeze. I request USD900 withdrawal, it was approved after 4 hours.
I continue talking to the scammer and when I told him I withdraw USD900 he was rather upset and started slandering. I gave him some excuses and said sorry.
Nevertheless, I managed to convinced him by telling him a big lie that I was flying over to meet him (I work for Aviation industry, so getting a ticket is a jiff). But I need to quarantine 14 days, so we will meet later.
He then top up 20,000USD to my account as he promised earlier, and chase me when my 20,000USD will be ready?
I buy time and told him bank clearance, need 4 days cause it's weekend, and it's a big sum I transfer from HK to MY, bank is asking me for documentation to confirm it's not money laundering.
Since I had 20,000USDT (from him) + my own 2100 USDT, I wanted to tell him some story before I withdraw. I was actually at the police station, trying to make a police report, then the police say, if you can still withdraw, why not you take the money out before they freeze it. Hence I did a 2100USD withdrawal and 2 hours later it got approved!!
I am so bloody lucky to have gotten away with the scam, manage to withdraw all my principle back with an extra RM10 LOL..
