I really don't understand people whining and moaning about the lack of marketing from the development team.
It's not only about lack of marketing. It's also the way Rijk runs his outfit. After two weeks with him you will know. You just get the feeling you can't trust him, because he wants you to accept 100% what he says even when things don't add up and his explanations don't sound right. Oh, he like to blame market manipulators and demon traders. Or "bad luck", or "bad timing". Nothing is ever his fault. If you put good money into this coin or any investment vehicle for that matter, you really want better treatment, better leadership.
My opinion is the complete contrary. When I have had to deal with him on a personal level he has always been completely upfront, helpful and honest.
If you still hold Gulden then my advice would be to get active and do some marketing. For your own gain regardless of your misgivings about certain people. You'll feel better for it I'm sure.
What do you believe is the reason the project is not higher up on this site below? I am using Gulden as an example of how a project with good potential can fail without marketing.
