I certainly have some serious doubts as to the integrity of their operations. I exchanged TUSD for DAI knowing DAI was 4pct off it's peg and fully intended to leverage that. So they took my TUSD and exchanged it but it's been held for 15 hours due to "technical issues" with the wallet. Meanwhile all other ERC20 tokens are working fine. Now it's down 1pct and likely falling while they continue to assure me it will be resolved. It was a pretty large amount. Sure looks like they are playing the spread on a stable coin that's off it's peg. Not very cool in my opinion, nor very ethical. Stay away.
