So, this is the service of cashback, right? Can I already use it while shopping on Aliexpress and so on? Does it work as ordinary cashback services?

I don't think you can already use it as it is still in ICO.

Ah thank you,i thought that there is maybe some beta available where people can already start sung cashback service.I guess ill wait a bit then

If there will be a beta I doubt you will be able to do that. Beta will be used for some general open testing and that's it.

I agree, this segment can be tested in a different way, I do not believe it will be an option for cachback during the BETA testing.

Can someone from the team comment on this? Will there be some open beta?

Well, according to the roadmap open BETA is schedule for Q1 2019, so yes
