If you check this twitter account, this is account of well known indian crypto user followed by big crypto influencers and projects. I accept that only one tweet is not enough to start scam accusation but If you check out Trust pilot review then it is clear that this is not only case and many people facing withdraw problem.
I personally consider influencers a big misconception. They certainly did not gain their influence exclusively with good and accurate information, and for a monetary reward, they will publish anything. Their modus operandi is to publish bombastic news the real truth is not the most important for influencers.
Once again, to be clear, it is not my intention to defend this exchange, even based on my intuition, I think they are closer to the description "scam" than trusted. But that's just my opinion, and I can't make accusations just based on my feelings.
Of course, there is no possibility for me to send any deposit there, certainly not $16m like some smart influencers who share pieces of advice.
