As you said it's just a common trend and we've seen it all before, bitcoin wil rally again in no time to 15k+ it was just scared money and hype over futures, after the peak always comes the fall. The only thing I would say when comparing to the major bear market after mt gox is that then most were using much smaller sums of money as the whole market was smaller, now some holders are playing with life changing sums and so it's no joke.

This was bound to happen especially the price rose in last couple of days was just insane. Had it taken a week to reach to this level would have being more stable than now what it is. Fall is for sure and bad part what I feel is that this fall could be more than expected and can break below 10k. So just thinking should we actually continue holding some btc or sell it for now?

Big media attention = fresh cash in the market -> price skyrockets.
Two days later, whales sell and profit for a nice Xmas present.
In two more days, new investors panic about their loss, they will sell at lower price and whales will get back in till 20k price.

Yeah, bitcoin's price is decreasing. But I am sure it will bounce back to 16000 dollars within three days. Its just a correction. Many new traders are selling their coin. That's why this price fluctuation. And in my opinion, its the best time to buy some coins and keep it in your wallet. Because after this period, their will be a sudden surge in its price.

I think what is happening is just what usually happens on forks. People bought bitcoin, in order to get more from the bitcoin futures short. They will then sell bitcoin for the price to drop and get profit out of futures. They can then go long on bitcoin, and use the profit they got to buy bitcoin at a lower price. They will try to keep this roller coaster, and get profit from both sides.
Those who are not getting in to futures, are probably selling now, because they expect the price to go down. So they will lock some profit now, and then buy again at a lower price, when BTC gets pumped back up. Bitcoin will probably continue like this until ETFs are launched or lightening network gets deployed, and BTC actually become a payment method.

I managed to sell at $16k and I bought back in yesterday at $14k, and all signs are pointing to up now.

I'm happy with the outcome, and I wish you guys the best of luck too and hope to see $20k by Christmas! I used to think we'd be lucky to see $13k by the end of the year, but I was way off
