Seems like a ponzi scheme to me. Their public address : 16V8yGZBKpjKBEVWUzYstP7wBr4U4MAWGj. They only received 1
BTC.
Which address did you sent to?
-MZ
The address you send to (deposit address) is generated per account (and can be refreshed/re-generated by user), just like what normal exchanges would do.
How did you know they only received btc through 16V8yGZBKpjKBEVWUzYstP7wBr4U4MAWGj?
AFAIK, 16V8yGZBKpjKBEVWUzYstP7wBr4U4MAWGj is not their public address.
Check one of their cold wallet address
