You are being completely paranoid.
I know someone who is having a problem so I reached out in the hope that those with far more knowledge than me can provide a little help or information.
It is not bad to be paranoid if it will save you from losing your funds, because you distrust new and suspicious services and do not use them, until it is 'proven' that it isn't run by scammers.
You haven't said what the problem is, however, if the 'person you know' deposited money into this exchange and they are being asked to deposit extra funds in order to be able to withdraw, then tell the 'person you know' that they have been scammed.
