For sure mate you will be rewarded with thier tokens since you will be submitting your own photosvon thier website.

Personally, for me, a huge plus is that the platform will be implemented photobank, where you can sell your own pictures.In addition, likes are converted into cryptocurrency. That is, I can just put photos from photo shoots to attract customers and get tokens for it.

SELFLLERY is platform that connect advertiser/seller and users/buyer, they don't need that content form themselves. And if you mean why they didn't just use currency like their or bitcoin instead of creating a token, they can do that if they have the money to build that the platform, but since they need to fund their project, they started ICOs that requires to issue a token.
Anyway I read their whitepaper that YOU tokens should not be seen as an investment, but they will have some value on the cryptocurrencies market.

Selfllery is not being every once choice as we can simply use it and make money there was loads of supporters for selfllery now as the concept is unique with an excellent road map it is being the better choice for all the investors.

Don't worry about that, we can know this project is not the unique but their team keep hardworking, you can invest or not, but if not you lost a big chance to earn profit from Selfllery.

Investing into this project will truely be much profitable ahead and also i am sure that the team might have collected good funds as the project is really much famous now and hopefully it would have attracted several good investors to their project.
