OP has gone offline since 27th June after posting this scam accusation, did he leave after hearing a fake story or not. One thing I am surprised to see is newbies who are victims of thousands of dollar scams, they come here and complain, this means they use different mediums before doing these deals silently because they never post asking for suggestions about any website before depositing money. OP has not provided any relevant evidence here to prove his allegation. So let's wait and see if he ever comes online and gives any reply here.
Not following up on the story is not good especially if it's a big amount we have so many questions that are left hanging, if it's true that he's been scammed by following the Youtuber's advice then he has a good case to bring down the channel to avoid many of his followers from getting scammed too.
This discussion for me is questionable because he is not posting valid proof like screenshots of conversations or transaction records but at least we discover trading platforms that are questionable and this is another post about not trusting easily and doing research first.
