One of the strongest qualities of Signatum is its name.  I think it would appeal to medical, academia, and insurance purpose due to its Latin roots.  All of those areas are big on paperwork and bureaucracy which is the antithesis of many cryptocurrency ethos.  But yet Ripple panders to the banks and institutions and it may live even with such an awful name.  What is it? Chips?  Candy?   The SIGT market is nice for a proof of a working coin, but it is not new and it is reinventing the wheel.  Devs time would be better spent working on more difficult problems.  The encryption of private data such as for patients or academic works and research would be useful and encryption method and delivery is the best value.  To gain interest from those areas the development team would need to make better practice of written documentation and research and rely less on trendy communication like discord while I do understand it is good to talk to the community - devs should be working not talking directly to community.  Do they have a someone who can handle the communication for them?  We shouldn't expect them to social/coms and develop at same time that is not reasonable.

The plus is that many large beaurocracies use 3rd party tools, especially education, and with the development team might even receive funding if they genuinely pursued it.  It might sound silly to say a name is so important, but with SIGT it is a strong feature.  SIGT team should recruit people who know how to write proposals and ask for specialized help.
I'm holding my small amount of SIGT.  Good luck team!
