Many thanks for this link. It was quite informative. I understand now that there are multiple factors affecting the price, but its generally good news for the future. Except if the US Gov decided to make it illegal I guess we will have to go to Japan then or maybe nothing will change then?

I would really appreciate any clarifications on the following if possible:

1- In the video they said last year they cut off half of the quantity of BTC to prevent inflation. Who controls that and what happens when they release it back again on the market. Would the price drops back again?
2- It also mentions about the last month's change in the technology code of LiteCoin so it became faster in transactions. How does that affect BitCoin and is it possible to implement the same fast technology as LiteCoin?
3- How likely will a pullback in the price happens? Is it possible for it not to happen and the price continue going up?

Thanks.
