Hahaha its not impossible that the bitcoin price goes up, because we all know that the stability of the price is not stable and change in every hour.
Yeah actually I am same with you, hoping bitcoin price goes up someday atleast reach $500, but I cant see anything that can become a trigger to make its price goes up rapidly. With Greek crisis, its price went up just around $50.
Of course is a risk, Antonopoulous always says so himself, BTC is very high risk investment, but as should you know, if you play in the high risk leave, you play in the high rewards league (assuming big losses league are included, but things look good).
I prefer to do sport gambling then, which dont need long time to get the result. Its really very risky to make bitcoin as long term investment.
