While someone is manipulating the market, it’s almost impossible to predict the trend. But I am sure that all abnormal events with regard to Bitcoin recently have only one purpose: to get more coins. 
We can analyze the move of 180,000 MT coins yesterday in three perspectives: 
1. Innocent story. That is, the coins were indeed stolen by thieves. But this account has never been moved since 2011 until yesterday. Are the coins stolen yesterday? No. So this story does not hold. 
2. Rogue story. MT decided to swallow the 850,000 coins. But if it’s true, MT should be wise enough to do it before bankruptcy protection, rather than to move the coins under the surveillance of the world now.

3. Conspiracy story. They just want to make people feel that the 850,000 coins will be sold, and the selling would be an unprecedented disaster for Bitcoin. There are two flaws in the ‘break up’ of coins yesterday: first, Bitcoin can be transferred from one account to ten accounts, so they don’t need to move coins from one to two, two to four accounts. Second, if they want to "whiten" these coins, they should mix into a large amount of other accounts to make tracking impossible. So, this is actually a man-made show to be intentionally seen by people around the world. 
Conclusion: this is a conspiracy story. 

Bitcoin will not rise sharply until the problem of 850,000 MT coins is resolved, because the possible selling of these 850,000 coins will suck all the money inside the market and lead to a disaster.

So, the market maker is sure to solve the problem of 850,000 coins before he begins to pull up.

My suggestion: continue to firmly hold your coins, and do not pay too much attention to price fluctuations. New comers can build your position part by part within a month in order to get an average price. For the short term, if I have to predict, I say the low point would be approx. 3500 RMB in China, and 580$ in foreign markets.

Altcoin index today is 8.55, down 1.3% compared to yesterday, which means altcoins dropped 11.3% when BTC dived by 10%. Because LTC takes 2/3 of the altcoin index, so let's make an Altcoin Index II, which excludes LTC, altcoin index II today is 3.32.

Altcoin market is bleak today. The confidence of altcoins’ market makers have been seriously injured by the MT problem. They are worried about the possible big dive of BTC as well as the collapse of trading centers, so they would not increase their position for the time being. When BTC market recovers, altcoins will have a retaliatory rebound.
