I am with you...all my steem is going right where it is...it is not moving. This blockchain is going to be one of the best stories of 2018 and STEEM will follow along with it.
Anyone who has profits now, that is a mole hill...go for the mountain.
As for exciting apps, DTube is awesome since it is so simple that any youtuber can use it. The other is zappl, which still needs a bit of work. However, think about all the tweets that go out and the option to do the same thing but get paid for a zap.
2018 will be huge @acidyo.
I am really looking forward to your project...it is exciting to see developers producing their own stuff.
