Bitcoins value and price will fluctuate over time but in the long run Bitcoins price and value will go up.
Whilst Ido agree with you, we can't be sure. We are all intelligent here and even as someone who is a partner in an exchange/mining pool creation, I still say BTC could crash and burn one day soon. Today, tomorrow, ten years.. We can't predict the future, but we can educate guess.
I'm seeing a $800-$1100 bitcoin by mid June personally. Hopefully we break the $1000 barrier. Weak hands stay away!
