Excellent post! This is a very valid argument for the merits of bitcoin and the value it has in terms of usage.
It's great that buying bitcoin is becoming more accessible. That also means that it is becoming more easily monitored, however. Easier access for you means easier access for them. So if it's something that you're trying to avoid being noticed for, extra precautions need to be taken of course.
The thing that amazes me about bitcoin now is that you can literally walk into a shop with cash in hand to purchase it. Or you can meet a fellow from localbitcoins who will take your cash and send you coins. It's about as anonymous as it gets. Or is it? Could these people be working for the tax authorities?
All those who are looking for investing of their money prefer to make an investment at a place which can then help them in having more money as more profit will then help them in having a chance to live a better life. There are investors who are not only investing in bitcoin but they are also holding most of their coins as this will then help them in having some huge profit after some years.
