I'm keeping an eye with this new one that has just been launched, Virie. I see a lot of articles and posts about it lately and based from what I've read so far, it looks promising because apparently, it does not require a third party broker because it's not a payment system with a market but it's a market in itself with a very user friendly payment system. If you want to know where I have been reading about it, it's here: https://www.annerainwater.net/
