6 BTC would cover all of my time for a full month, allow for budget of resources, and allow to tip the people who help.
In some places in the world 6 BTC in a month is a very good salary. Is this going to be setting a precedent? Will another 6 BTC be required for development next month etc etc.
I am not saying that you (the developer) are not doing great work with Bitmark, but I do think this is potentially a dangerous path. Should the reward not be in the projects success?
Ideally we would all have the resources to be able to focus all of our attention singularly on Bitmark but in reality with living expenses it's generally not going to be possible with out some method of sustaining oneself.
Coinsolidation/Mark has been working like crazy since this idea was born and I don't think he's had much time for much else. Since there is no IPO or no premine that can be sold off the alternative is development funded by donation, or in this case crowdfunded projects that are separate from Bitmark but still add significant value to the project.
This is an issue we've been debating for a long time now, how to ensure sustainable development and proper incentive. Projects like this should pay for themselves many times over, but it's an investment in both Bitmark and an what is basically an open source startup. People will also be able the take to project and expand its scope as an internet value transfer system outside(but still connected to) Bitmark. But that comes after.
