I’ve spoken to this type of request from this same person before, and so my reply is probably easily predicted:
ZCG, do not fund this.
Marketing + Workshops at Global Conferences (mostly expensive jet fuel and hotel accommodations, also event tickets where we’d pay to market among stiff competition) is not effective use of ZCG’s budget.
Last crowdfunded event: “34+ new users” for 50 zec. This grant is 5 cons for 178 zec (today’s current value). Expected value is about 121 new users calculated by zec, or if by con, 170. Are 121-170 new users worth $75,000 !? If you gave 1 Zec away to acquire each new user, that would be less expensive per user.
Home-made marketing could be way cheaper and probably much more effectively done online. Less high-cost physical world concerns, more impressions. Build buzz, brand recognition, online communities or projects, conversation, support.
Face to face is good, but also whoever is contacted at cons will have dozens of competing projects vying for attention in a short period of time. Theoretically, a watched educational video to introduce zashi for example, might not have that kind of distraction.
A better marketing play at conferences would be to present something, as a talk. Usually that would be the icing on the cake for success, maybe from funds spent in better ways, like new code, novel or enhanced products, research and development.
(Also, code review, refactoring and auditing is important.)
Assuming readymouse and fabacab have coding skills, I think the best thing for zcash would be to use the brain, CPU and fingers! Save on gasoline and rentals.
If marketing is really the way they want to go, please consider the cost-benefit. Are world wide con-hopping tours to meet with distracted devs is a good value?
