probably not , because the halving block reward is getting closer and closer which should be by the end of the next year , so there is a huge chance that the price will rise like hell . maybe multiply if the demand stays the same . and if it rise it will be better .
yes not really dead. Maybe its not famous and only few people know what is bitcoin and how its gonna work. But bitcoin is alive and many company or business still using it.
I dont think there are many company that use bitcoin as their payment, may be some of them use bitcoin but mostly they dont even care about bitcoin problems since they strong in fiat. If bitcoin has been used by many company I am sure the price will go to the moon in next year and everybody will start to invest in bitcoin for sure
All big companies are aware of Bitcoin and will use it as it will fit them. You saw how IBM used it for advertising their Cloud services in Brazil. Lot of projects are worked on and lots are already alive. But as normal they dont attract as much interest as they would 2 years ago.
