This one is an invitation and it was made because a thread was created seeking for an advice or direction. It could be a scam attempt but I am not so much bothered about this as a red flag. The one that marvels me is when there is no such public post made seeking for help. You will just see a random private message from an unknown person, suggesting an investment opportunity and someone will fall for it.
If you want to be careful with your money, don't trust someone you know with your money, let alone someone you don't know.
