Apart from the post points you have mentioned for me bitcoin gives an immense stability to me by providing Internet based income. This income is additional for me with which I can buy many stuff for me and my family. I'm grateful to it in many ways, as it has given the financial freedom which I couldn't get from real job that I'm doing. Moreover time is the barrier in real life.
There are many reason why I chose bitcoin, But I will give 1 top reason, that is decentralization of bitcoin. Because of this features of bitcoin all government in each country are not capable to control it. That's why we bitcoin enthusiast called "The bank of our own savings".
Undoubtedly, majority of the investors are attracted towards bitcoins because of their decentralized nature. Decentralization gives them complete control over their money and they can sue it anyway they want without paying any tax to the government. What I like most is its anonymity.
