Btc has run too far too quickly possibly due to manipulation by hedge funds. But it wont crash too hard I think. By guess is undervalued alts will rally hard now. Just a guess
The fall of the altcoins that happened on November 30 was not even the correction of the market. It was a temporary event just a trick of big traders to earn a lot. I do certainly believe alts will follow on growing.
I'm just buying alts and now profit is going up!
