2020 will be the year when more governments are going to be including blockchain in their systems to become more transparent and more reliable in order to offer a better service to their citizens.
What are the reasons?? I don't see any news telling more governments to adopt Blockchain or Bitcoin this year. If you got the issues from some sources, it is better to enclose here as the proofs. But if it is only in your opinion, I'm sorry to say that it is doubtful.
BTC will be more popular this year because since 2018 was mentioned a lot if the media, even when they talk in bad way about it, Bitcoin keeps growing, even negative news is good for the network of networks!
Bitcoin is always popular and more than other crypto coins. Even in 2018, when the crypto world is in a bad season, Bitcoin still became the favorite for investment. You said, "it keeps growing", means that Bitcoin is always safe to buy and hold.
