I only came up with 8 niche crypto business sectors. Please let me know if I am overlooking any sectors. Again, I want only the largest cap company in that sector, but not if it has ever been ran a Dictatorship:
1. the largest (biggest market cap) data storage company is Maidsafe
2. the largest records database company is Factom
3. the largest social networking company is Synereo
4. the largest music monetization company is MUSE
5. the largest public Turing complete computer is Ethereum
6. the largest anonymity solution (omitting DASH) is BitShares
7. the largest file swapping service company is Florincoin (The Alexandria Project)
8. the largest domain name company is Namecoin
So to summarize:
1. did they delivered any product so far? Last ten years, perhaps?
2. Namecoin entered the market earlier
3. Facebook?
4. iTunes.
5. Cloud Computing. The better approach to rent CPU cycles.
6. Bitcoin. Use a darknet search engine on "Mixers"
7. The Pirate Bay
8. DNS runs just fine if searching for an alternative
There are no such "niches" to deploy. The Dictatorship argument is void, proof: Apple. Microsoft. Oh, Facebook. Google.
