why I believe Bitcoin is a good technology
Because Bitcoin is an electronic cash system that has many conveniences and freedoms.
Bitcointalk has been playing a big role in Bitcoin history and I want to take part. While it is not easy to understand Bitcoin, we all have a chance to understand and collect Bitcoin.
Because Bitcoin is so difficult, we have experts to explain us details and once Bitcoin education will become more available and easier to understand for normal people, Bitcointalk seems to be a great place for a start.
The Bitcoin Whitepaper is reading that needs to be read to the end several times to find an idea of what Bitcoin is, even though later you will find other readings that discuss Bitcoin.
If I were an expert on Bitcoin technical matters, perhaps I would serve you well via the bitcointalk forum utilizing the personal message function.
Anyway you are right. This Bitcoin forum is the most open place to discuss Bitcoin as long as you are willing to do so.
