i think that it is still way to early to have any real opinion about bitcoin at this moment because it is still fairly new on the market and there is also so much news going on about it - good and bad, wrong and right. so it is difficult to form a concrete opinion about it. looking at its performance history we can see a upward trend then followed by a slow downward trend, which is typical for such an investment product and all thoughts and opinions are typically speculative.
