From a marketing perspective yes, the wallet update absolutely should have been delayed at least a few days, as not to be overshadowed by the other announcements. Investors ideally want a nice steady stream of updates to maintain confidence. I see the massive future of blackcoin and it doesn't affect my investing decisions personally, but at the same time I want what's best for the BC community, and even something like this that may seem insignificant to some DOES make a difference.
I have an extensive background in marketing and business development, and was hoping to be able to help sooner, but my life is very busy. However, now that I feel I am fully entrenched in the future of blackcoin, I have set aside some time next week to get in touch with the devs, blackcoin foundation, etc to see if they are open to some planning. I'd like to get an idea of their current marketing and biz dev efforts, then present a revised marketing outline and form a core team to execute if there is not one already.
I will post updates here next week as I move forward on this. In the meantime, if anyone is so inclined to assist in any part of this, please post a reply or shoot me a PM.
