While the current network and performance issues are very frustrating, I urge everyone to remain calm and constructive. SHOUTING IN ALL CAPS, criticising developers, or using foul language isn’t going to have a positive impact on the situation.
A lot of people are working very hard to mitigate these issues.
These are all part of the growing pains of a new technology. Zcash will end up better, stronger, more robust and better performing as a result.
