From my views towards the bitcoin there is no chance of price of bitcoin is going down because nows a days the popularity of bitcoin is countinously increasing day by day and demand of bitcoin towards the people is also increasing that's why the number of user of bitcoin is also increases so that the price of bitcoin is also increasing and there is very less chance to decrease in the price of bitcoin but the fluctuation in the price of bitcoin is always take place in the market.

https://www.clivemaund.com/article.php?id=4444Let’s not be churlish about this, however, it is important to give credit where it is due. Those who got in early on this Bitcoin mania are true geniuses who have every reason to feel proud of themselves, having made themselves a fortune from even relatively modest stakes. The problem for many such investors though is that they don’t know when to call it a day and jump ship – many overstay their welcome and end up losing most of their gains. If you, dear reader, are one of these fortunate individuals you should get the hell out with the minimum of delay and consider yourself lucky. Sure you might miss some more gains short-term, but when this thing goes down it will be a lot faster than the Hindenburg and leave behind a massive impact crater, as unbridled greed changes in a flash into visceral fear and blind panic and all the recent lemmings disappear straight over the cliff edge – it will go into freefall and bids will evaporate.
https://www.clivemaund.com/article.php?id=4456There are hordes of young and not so young fools out there who are now “champing at the bit”, wanting to buy Bitcoin. They watched enviously as it rose into the Stratosphere, and now after last week’s smackdown, they can seize their chance to buy at a heavy discount from the peak price, thinking they have gotten hold of a bargain - ignoring the fact that this “heavy discount” is from a massively overinflated price. After all, “buy the dip” has worked like clockwork now for years, right? – and this is another dip, is it not? WRONG!! – this is not a dip, it is the initial plunge of a bearmarket in something that got insanely overbought and has now burned out.
IMO If you already made a nice profit of Bitcoin it wouldn't be bad idea to get your investment back and secure (some, if not all) gains. A common error in trading (specially for us, newbies) is not setting target prices. Once it reaches 15K you want 20K and then 25K and so on... but what if that never happens or if it happens after long time (remember BTC "correction" in 2014)? The crypto market is insanely volatile so caution is always advised.
