I Believe we are up for a surprise that we'd be surpassing 400 in the next 6 - 12 hours , hang in there folks! 
It's gonna be a ride up!
You'r prediction is turning out to be right, mate It's gonna be a ride up! 
So, one prediction for me - when will the price fall below 280 BTC ?
Need to buy my first bitcoins (4-5BTC), investing half of my savings.
Welcome aboard. Just buy and wait you can always step out if it drops.
I myself bought 5 extra and I felt bad about it but it's a high-risk high-gain investment.
Last time I won big with mining and doubled my money.
You might make $500000 with those 5 BTC or zero.
OInly invest in what you are prepared to lose and have an exit strategy.
