I misread a decimal place on my wallet screen and accidentally deposited like $15 more than the original quote requested. Thought the swap would freeze or get rejected, but the engine processed the whole extra amount with zero issues.

A total scam. I swapped $1,500 worth of Bitcoin to USDT through my Trezor. They froze my funds, demanded KYC and additional proof of funds, and I provided everything they asked for. Despite fully cooperating, they still haven’t completed the swap or refunded my money. What makes it even more frustrating is that they respond to my emails almost instantly, but every response is basically the same generic “we’re still working on it” message. They reply quickly without actually providing any meanin

Hello, Liad! Sorry to keep you waiting like this. The thing is, we take AML very seriously: our Compliance department works with certified tools and agencies, so they may need some time to investigate each case. We'll make sure they update you as soon as possible, and we hope for your understanding and patience.

Honestly works fine. Pushed 400 usdt to solana last night, took around 6 mins total. You just gotta make sure you aren't pasting the wrong network address or obviously you'll lose it.
