All valid points and those are the only that I can think of that anyone can really ask for when choosing to use bitcoin in the first place. 
There are lots of reasons on why you should choose bitcoin. First, it is a profitable investing site. It's value is unpredictable. Also, it creates faster transactions. If we'll just have passion on it and we'll just work hard for it, we will gain a lot of profits from it. It is a way to success.
