Obvious scammer.

Telegram chat between him and me: https://imgur.com/a/btgHhQT

Summary:
The domain has created 5 days ago (https://whois.domaintools.com/dentawallet.com)
He came up with this story that he is with his platfrom from three months.
The withdrawal is locked until 28th of this month or something.
He is willing to give the password and stuffs
You can play ROULETTE I guess.

Anyway I did not finish with him but I know where it was going. They will ask for a deposit to withdraw the money. The guys will ask you to pay or something and once they will unlock then he will pay your money back and will share the fund in the system already had before.

All bluff. Ultimately the guy is in control of the site and the address will be one of his address. Whatever you will pay, you will end up losing it.

This is a very old scamming techticks. Be aware.

Flag supported.
This trick has been done many times and it seems it's popular trick but not a good one.

I think the topic should belongs to Scam Accusations.
