Sonm looks like a good bet to me, they will release a big surprise news on December 25 during christmas. You can find more information on their website at Sonm.io/miracle I think
I think they are going to release a new wallet + announce a partnership
Yes they are going to release their testnet on December 25th. But I don't think that this is the "secret" news they are going to announce that day, cause it isn't a secret after all.
I'm hoping for a major partnership. This would cause the price to skyrocket. The growth in the last weeks looks also very healthy so far.
