In my opinion the biggest focus should be on building a strong Development Community. Killer DAPPs will trigger their own User Communities, which all will merge into the Cardano family. Charles promised 10k Plutus developers in 2018 Plutusfest, that should be the target for 2021. To allow for such killer DAPPs we need marketing for developers (Blockchain and functional programming), vc funding (in place), investments into creating professional Development Tools & Utilities, interoperability of Cardano with other Blockchains, educational content and integration facilities with Value Added Services.
Another stream is supporting Stakepool Operators to mature with the evolution of Shelley, provide financial aid to them when ADA is below certain value and also to incentivize them to be much more transparent about their operations (live KPIs and pool health online, etc) and have professional web presence and identity. Consider incentivizing established and reputable SME IT companies in Africa, Asia and Latin America to run stakepools.
An other important stream would be to educate, empower and incentivize local Communities where the future users for these killer DAPPs are, mainly in the counties of the unbanked 3 billion. Discover and engage the leaders, the authentic voices and influential people of these Communities and offer them a deal they can’t resist. Consider even running a Cardano MLM like franchise system (!) to onboard new users to the DAPPs.
The current Community (more in the wealthier, Western part of the world) who “invested” into ADA needs the regular content, updates and transparency on the roadmap execution so they further speculate and envision that Cardano will be a game changer, that incentivize them to stick to their ADA holdings keeping the cryptocurrency strong a healthy Ecosystem needs. I would expect an AMA from Nathan or the CF Council at least on a monthly basis, but as said Charles oversees this so maybe its not needed. Additionally as this Community is the major holder of ADA, it’s essential to educate them on the roadmap and responsibilities that come with Voltaire. It would be great to get a proper upgrade of Yoroi and Deadelus to efficiency support the communication, collaboration infrastructure that will be needed for the governance of Cardano. It has to be done in a way its fun, joy, social and sexy. Not boring corporate design.
Finally I believe a country like Rwanda might be bootstrapped for adoption with a few of the killer DAPPs (p2p marketplace, p2p loans, crowdsourcing, dating, gambling) and having Charles donating 2-300m ADA of his holding to a selected ~100k people (1% of population) in the country, who meet certain criteria, commit to certain obligations and limitations and have the right infrastructure. Once Rwanda gets adoption it will spread to the neighbouring countries.
If there is any money left, spend it on creative guerilla marketing from the Community (such as street art).
These things here are not new, and have mostly been said 2 years back. Why they did not materialize back then and will they now? I think without the killer DAPPs its not possible to make significant progress, so the time really comes with Gougen. CF had to wait for IOHK to deliver and they should not be criticized because or this wait and delay.
