a) personal bonus to the referrer
b) common bonus to the community as a whole
Q: who will decide how to spend common bonuses?
The concept of profit distribution is somewhat like that: when profit is created (usually by users paying to developers), SRG takes part of it as comission and divide it in three parts - one part goes directly to users invovled in referal process, second part goes to SRG for development and other purposes and the third part considered as a net profit and later distributed among the ALL token holders as dividends. I hope you understand it's just a simplified way to put it. You can find detailed description in our WP, page 14-15 and so on.
