And everything changes so quickly in technologies. I often do not have time to keep track, as everyone has time to change.

Damn, guess the correction is imminent.

Like 20days after the OP's post, we saw the peak of the first bitcoin bubble.

it is possible that many bitcoins can change our country so it is better to have bitcoin make our world and nation better than just bitcoin.

Bitcoin has successfully crossed its initial stage. Bitcoin is being widely accepted nowadays all over the world. Bitcoin has reached price of about 735 US Dollars. It is expected to reach $1000 by end of this year. Bitcoin is the future of money.

I think so. I have read people said, "bitcoin is dead", even you said bitcoin have died for 89 times, but bitcoin is still here. remember, bitcoin is addopted as accepted money in some countries like Japan, Russia, China, etc. and now we can see there are a lot of shops around the world accept bitcoin as payment. I don't know whether bitcoi. will be accepted as money in every country or not, but I'm sure it will be future money. just remember money definition.
