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.
You should choose Bitcoin because of the fact that you can make some extra money which is always a good thing if you ask me.
Bitcoin is the perfect option if you you are looking for an extra income that does not require much time.
I think not just for extra income but bitcoin is part of the future where if you want to keep up to date you must use and choose bitcoin because I'm sure someday bitcoin will definitely become a global currency. because digital currency will be used. I'm confident with it
I do understand your point of bitcoin being an extra sorce of income, besides that being part of bitcoin its being part of the future, even knowing that a big part of the people wont never use or believe into bitcoin. In the end several people are inside of bitcoin to make money, dont be ceptical, if i offer you 1000 dollars for 1 bitcoin you will sell me unlimited coins right now.
