If I say we'll have a retest of 300 within an hour and I'm right, will I become the next prophet of this thread?

(If I'm wrong, obviously nobody will remember anyway, people only remember those predictions that came true.)
That's not a very bold prediction, but you are welcome to be a prophet. We are all prophets in here. Predicting the price of Bitcoin is like sex and driving, we all think we are good at it.
I have to say your last assumption is incorrect. I, for instance, do believe I'm good at sex but
I'll never be a good driver for one simple reason: I'm a woman. 
That's why I need bitcoin to rise to the moon - so that I can buy myself a car with a chauffeur included.
You just need the right footwear.
