That is true, nobody knows what the future of bitcoin will be. There are different opinions and even being different, they make a lot of sense, as the probabilities are infinite. I believe adoption will continue to increase, although I don't think it's mass adoption yet.
As adoption increases, awareness will increase as well, as consequence. Bitcoin has good chances to become a very strong currency in the world, especially because it has overcame a great enemy: the mainstream media. If nobody listens what media says, bitcoin won't be defamed.
The media coverage has obviously increased, and it has become more positive. I still remember the case during 2013-14, when the mainstream media was very negative in its coverage of BTC and was portraying it as a currency of the drug dealers and criminals.
Adoption continues to increase, but at a much slower rate when compared to 2017. The sharp correction that we had in 2018 slowed the adoption process. But I believe that this is just a temporary phenomenon. As the exchange rates increase once again, the rates of adoption will also pick up.
Generally, with those who believe in bitcoin usually make a positive prediction on cryptocurrency. Personally, bitcoin should be considered one of the greatest invention of the world. Although it's short of official recognization, still it's gaining in popularity every single day. Bitcoin was born about 10 years, and now it's continuously on the way of gradual development. Like a famous person, it's been passed through many bad as well as good rumours, plus critisism, even the ban from many governments. But after all, no one can prevent it from developing. Exactly i believe bitcoin will have a bright future, hopefully we will soon use it officially like the way we use fiat currency.
