Some good discussions going on today. I see both sides. one side states they miss deadlines by a huge amount of months and give very little feedback as to the reason for the delay.
On the other side they do say they are doing their best to ensure the update works perfectly before they release.
Either you believe the dev team that they truly care about doing the right thing for the update and will let their work speak for themselves. If you believe in the project being successful and eventually released with no issues then it doesn't matter if it is delayed. on the other hand if you expect to make a profit in the near future it can be frustrating when they miss their deadline.
I bought several crypto coins and tried using them and i saw that Gulden was way easier to use then the other coins i tried. Do your research not just with Gulden but compare to other coins. How easy is it to use, do they have phone apps, is their coin secure, is their coin fast to send and receive, see what other projects are going on for other coins and how long they take to release. I think the release will come, but I think it might be a few more months.
