It starts to move upwards again. I don't see any reason why not. Most investors I think invest again by this time. The sudden increase I think due to commitment of some to lay their money again in bitcoin and have serve their capital one again. It is pleasing in the eyes to see it grow its value again.

Yes,there is a sudden bump in the prices but now the price is slowly falling and it backs to $7700.I think this is due to someone who bough decent amount of bitcoin or all the crypto currencies because all the price jumped at the same time.

As well may be Mt Gox finally cashed out 1 billion and left the market so a huge amount of sell orders finished at once..

I do not care what the reason is. The thing I care about is the price of bitcoin has increased. Look at the chart of bitcoins have not seen the signs go down. Maybe now the bitcoin price will go up more than 10k

This is Cryptocurrency, the price can go up and down anytime. when we expect the value to rise, but it turns the value down. and when we think its value goes down, but its value goes up. Cryptocurrency price is very volatile, so we as a Bitcoin player should not be easily surprised by the rise and fall of Bitcoin prices. this is natural.

Maybe someone who sold at the top and made huge profits during the bubble is buying back in so they don't have to pay capital gains tax.
A whale who lives in the US. Tax day is only a few days away right?

I have the advice for you that is to continue to hold bitcoin from now until the end of the year. You should trust me, I am sure with you that you will have a lot of profit. The chart of bitcoin is showing signs of increasing

I'm not sure the whale is behind all this. market movement certainly involves buyers and sellers. needs that exceed the seller. yes, I think this situation is really surprising because there is no evidence of previous growth. hopefully this is not temporary and will end well in growth on another day

This one was a highly manipulative pump from the exchanges. It might be an exit pump. Exchanges know our stops/liquidation price and everything. That's why the price pumped to $8k because all the open shorts were set to $8k limit. The recent altcoin pump was also done to gain more BTC to dump it when it reaches $8k. As there is no such Bullish news or FA that could have brought this huge pump. That's why I highly doubt this attempt. Over $1.2 Billion was traded in this pump. A clear pump attempt by exchanges. Now they will try to liquidate longs because people now will think that BTC is bullish and will take long positions. BTC can only be termed as bullish if it crosses $10k threshold. Before that thinking it as a bull market can get you rekt. Next some days are crucial to know the actual price movement.
