As a programmer i know that one month delay is still pretty good and i'm not even mad. It's really good that they find a hole and can fix it, because it will be terrible to find this after release. What i don't understand is why the hell they want to use SQLlite anyway ? It got terrible performance in higher number of inserts and updates. PostgreSQL will be much better choice.

But as an investor i'm pretty mad. Why the hell you say you can launch lisk on 12th april ? As a investor if you say "Lisk will be out in end of may" i will be completely fine with this. But reschedule release day every two weeks seriously do not help. A lot of people pull their money from big coins like ETH, and they was ready to invest in lisk. Now ? I'm not so sure. If you want it or not, crypto altcoins world will be always not only programming project but also community and marketing dependent project. Timing and comunity are, what make coins valuable, not utilities and stuff you can do with it. And don't take me wrong, of course i know new invented stuff bring more attention, but interest of people is the main goal of successfull project (not even in crypto world).
Well and now ? We got pretty much disapoinment/agry comunitty and completle messed up timing.

All in all, i don't want to FUD or scare anybody, i just want to share my opinion.
At the end i think if launch will be without any problems and will be FINALLY on scheduled date, we are still fine.
