First I want to say that I have some Bitcoin and I want to see it go to the moon. But I have some questions regarding the reasons that people give as to why Bitcoin is a good investment. 
Reason 1: You are in control of your own money - government overprint cash which devalues the dollar, but big influential people and institutions can devalue Bitcoin with a single tweet. Bad news, issues with mining, and other things out of your control can devalue Bitcoin.
Reason 2: Nobody can take away your bitcoin whereas the bank can confiscate your cash and lock your account - should I worry about my bank doing this if I am not doing anything that is illegal?
Reason 3: You can send it to anyone in the world - why would people want Bitcoin when you cannot use it to purchase in many stores? Plus ii takes too long for 1 transaction to go through.
Please correct me if I am misinformed.

If truly you love bitcoin then I guess you should be less worry about what the news holds, either being top influencer or the government. Because each time it dips based on one government banning bitcoin, or influencer like Elon putting a pause in accepting bitcoin for Tesla etc.., whales enters the market and purchase in bulks.
What you're yet to know is the fact that this same whales are part of the government officials, also the same top influencers who said a word or two to made your weak hands dump.
However, you should be less worry about why the demand for bitcoin as payment keeps improving... People prefers bitcoin because its fast, secure and easy and they're can easily turn to cash to purchase in stores that doesn't yet accept Bitcoin as their mode of payment.
As far as I'm concerned, Bitcoin and Fiat will keep working together, just like Gold and Fiat or Bond vs Fiat.
