What happened?
I'll assume you are asking about the price of GEMZ?
Poloniex has threatened to delist GEMZ. I'm not sure of the reasons why. Most of the time when they delist a crypto it's because of the lack of volume. People are selling GEMZ cheap so they don't have to transfer them from Polo if they delist. Sometimes they reverse their decisions because of public interest. I hope that's the case this time. If not, Polo will no longer trade GEMZ after June 3. It doesn't mean the coin is dead, it will still trade on other exchanges.....Bittrex for one.
In the development plan everything is pretty much on track. They have received the last payment for the final milestone. The foundation is laid and the app is working flawlessly. We await the masses. Now it's all about attracting more users to get the Attention Economy rolling. There is more coming for the Attention Economy when the advertising interest appears. They are working on Getgems Keyboard/PayKey....I can't wait to see what rolls out. That is what I am most excited about!!
