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.

Everyone has his personal reason to invest into Bitcoin. To survive, hodl, become richer, because of believe into Bitcoin etc. But the key moment in this question is new and good opportunities that cash or banks can not give, because those two have borders, limitations and different nuances. Bitcoin give people new opportunities first of all - like time economy, bordeless transactions, income and so on.
