why I did not find this latest update this December. is the team active in other grub like telegram? I still hope this project will be better later because I still hold storm quite a lot

They just started (about week ago) campaign of giving away 10 000$ for celebrating of iOS app release. It takes too long for them to make an updates, but by the little steps they approach their goals.
P.S. Also they opened back a referral system - if someone have not registered yet in their app then use my referral code VVPBNRER when you register - you will get 6 000 bolts for that immediately. It is great that you can get Storm tokens just for completing tasks in app. On the falling market I get more tokens when convert bolts into cryptocurrency - it is the time at least to get those tokens for free, which on the next crypto-hype can increase 100 times = in my opinion that is not explosion - that is just a normal price up when the project adopted by the masses and it takes a long time (I expect about 2-3 years). The project is legit with good product which can bring a profit and help some other companies / apps in the future. It will explode with increase more than 100 times only if they release a platform for freelancers, but at the moment they did all the things very slowly. Of course if Storm token will increase the value 100+ times - then the whole cryptocurrency market must have at least 1-5 trillion capitalization.
