how does lykke reward the shareholders?
What do you mean? Shareholders own a percent of the company, they are entitled to dividends, voting rights and any asset the company owns now or in the future. This would include licenses, offices, equipment and so on. In that sense Lykke is one of the only projects that gives you actual equity, it's not a digital protocol or a piece of a platform (I compare tokens or coins to "software licenses"). This doesn't mean an Adobe or Microsoft software product can't have value but is very different compared to actual shares in Adobe or Microsoft companies.
