Well voters HOLD LSK, vote for you people, that's why YOU can forge and contribute and share and donate. And voters don't sell it even if they could gain large benefits by doing it.
That's exactly how the system should work. And don't forget the most important thing about delegates: They are those who secure the network and process the blocks. And a secure and stable network is important for Lisk to succeed.
... we just want a bigger part of the cake...
Then do something useful for Lisk. Organize a meetup. tweet about it. Explain it to friends. Write a tool. Publish a website. Do ANYTHING, let me know and I'm very happy to award you with much more than only a few single LSK for voting. Help contributing to Lisk by increasing its value. That's how you will get a bigger part of the cake.
