Hello guys. Just got myself to read through the web and little bit of whitepaper. Project seem to have great potential so I'm thinking of investing some. just few things are a bit unclear. Where do I store the pay tokens? The wallet is so far only offering me to deposit the BTC. I don't see any wallet for the pay coins and so I'm confused about the presented 0.5% reward. Can anyone make it a bit more clear please?

Thank you
