i want 50$ a coin next year

I highly doubt that.
What was your prediction on btc/ltc/ etc a year ago? I'll guess you weren't even close. It could be $50 a coin by the end of the year (I don't believe this either but in this market it's not impossible).
I wasn't here a year ago. My prediction for November was correct, though sharing the correct one would be a mistake right? Others would take advantage of it.
I think that $10 would be more likely, but who knows.
