The site is not working right now & as I saw there are lots of users scammed. It's really bad.
There should be some scam accusations about them, right? Can you point out where anyone was scammed by simpleswap.io?
Those are searching a legit exchange for instant swap their alt-coin, I can recommend them to use ChangeNOW platform.
Recently I used it & it really works very smoothly & almost instantly.
They have also lots of others feathers also & also have their native token NOW.
It's a coinmarketcap listed token. You can check out here their platform for more details:
https://changenow.io/How much did the changeNow.io scammers pay you to defame other legit exchangers and then shill a scam exchange in their ANN thread?
I am leaving you a negative for defaming simpleswap and shilling ChangeNow which is proven scam in Simpleswap's ANN thread until you prove to use how Simpleswap is scam.
