In my personal experience, people that are enthusiastic about guns tend to be in completely different circles then those that are enthusiastic about crypto (or computer hardware in general). Of course there are exceptions (like myself for example), but hearing that there are gun store owners and businesses interested is very encouraging news.
Well, you are correct - that is the main reason we have the users guide. Many of these are just hearing about bitcoin and ethereum for the first time. So this is all new to them. Back in 2014, GUN was just too early for these types. But now, GUN is probably just what they are looking for - a better alternative for their payment system and a pretty good long term investment as well. That is why a lot of what we are doing is in keeping things as simple as we can and make it as easy to setup and use as possible. It seems to us, that will encourage more to try it, if there is not a dozen books an classes to sit through to use it.
