Contrary to popular belief, Bitcoin's purpose is not to "experience a bull run" so you can sell it to accumulate more of your national currency. What I'd like to see happen in 2019 is for more people to realise that freedom is worth whatever price it happens to be.
I actually like this so much,
"freedom is worth whatever price it happens to be." Very well said.
In response to OP, do you hold onto Bitcoin purely as an investment? One thing to keep an eye out for is the continued developments of the lightning network, which could be read about here:
which could be read about here, in brief.A piece of information you could be excited for is the launch of Bakkt- a company/cryptocurrency exchange founded by the owner of the NYSE that's partnering with both Microsoft and Starbucks. Expected launch is in late January.
I think most people should know by now that most ICOs were a load of nonsense and unfortunately a lot of people lost money investing in worthless whitepapers and anonymous teams. My opinion is that there is still value in a very select few of these projects, especially over the next couple of years. However, you're going to need to do some extreme due diligence to figure out which ones are not scams.
With regards to Google Trends, I agree that hype isn't necessarily the best thing to consider when understanding the value of Bitcoin as a whole. There are 10 years of work, development, and foundation that Bitcoin is built upon, and market cycles shouldn't distract that fact.
