Is Bitcoin Falling Time to Sell?

Bitcoin today is in decline, was lost more than 2 thousand dollars in less than 2 hours, worth at current price 12 thousand dollars, but why fell so much?
It had a strong correction in January in all years, January has a strong correction of bitcoin, plus the news of China's ban on mining bitcoin plus the Korean government wanting to ban bitcoin and trading houses, has dropped the value of bitcoin !!
Should we worry?
We can not get desperate and sell your digital currency asset, because the trend and increase the value, as every time bitcoin has recovered from several bad news has always surpassed and broke the barrier, I also say for the altcoins, do not sell, buy more now that's on the promotion !!
