I think that Q&As should be a regular thing for all companies, regardless if they have an ICO or not. Every investor should have the right and option to ask questions
You are right, it is nice to see that they are still doing the Q&As, it's a really nice method to stay tuned to what's going on in the project. If you don't follow them on a daily bases these Q&As are a really good source where you can get up to date about the porject. Great work!
