Everything can be in this world. It may also be that you're right, or maybe not!
But I'm still in my opinion that if this really should be a scam, then Hawala team has chosen the most complicated method ever.

Yes, volume in exchanges is decreasing and it will continue to decrease more and more. And it will be very difficult to buy or sell HAT coin (but the same thing will be for Hawala team, very difficult for them to sell if no products will came out). Now the book volumes is ridiculous. For this reason, when Hawala will launch the p2p exchange, the cash cards to buy cryptos price will increase dramatically. This is my bet now!
If they don't release their promises, the volume will continue to stay low, so they can't scam with a lot of gain. But if they really desire do scam us with less profit, they could have already done it months ago.

And more in this days Hawala is making the transition from the alpha version to the beta version of staking wallet and it will have more functions. So other work for them, why if it's only a scam?

Why Hawala team continue to send us the 15% reward? This will inflate the hat market, so in the case they would scam, they will have more difficulties to increase the price and to sell their HAT.
It is not a functional scheme for a scam.

Same thing for Kucoin airdrops, they have contributed to damp the HAT price.

Other important thing: while Hawala team has not already scammed us using our erc20 wallet private keys?
