Unfortunately I have lost a significant amount of money to these individuals who claimed they could recover my funds from a fraudulent online trading platform. I have learned a hard lesson from all of this.
One of Bitcoin's features is irreversibility of transactions. That means that once the transaction is confirmed and a few blocks deep, I can't recover it. You can't recover it either. Bitcoin developers can't help you nor could the President of the USA together with his staff. Additionally, any service that claims to recover wrongly sent, stolen, or hacked coins, can't do anything to help either.
Unfortunately, they saw a person who isn't knowledgeable enough about Bitcoin and has some money to spend. So they took you for a ride and once again you were scammed.
Too bad that you didn't know about this forum before the second scam. People do more research when bad things happen instead of doing it before they do things they will regret. That's just the way it is.
