The thing with bitcoin is not that it's unpredictable(it is to an extent but it's just as unpredictable as stocks in my opinion), but the fact that bitcoin price often swings from being bullish and bearish, even when the overall trend is bullish.
Just don't get too positive when the price is bullish or too negative when the price is bearish.
Even its bearish I don't think it wouldn't affect so much with the demand from new investors now, because its becoming unstoppable of its value to rise more better. We can't predict the price to what it may result but what is good for these following days, the price is not heading towards the higher value and we couldn't even analyze when will it stop. It keeps on surging and I am able to see the great possibilities that the previous speculations that bitcoin's price of $8000 will be a reality for few weeks of price fluctuations.
Bearish market will not last as well. Maybe the price could do sideways for a time being, but when the price pick up again.. ohhh, you don't want it because its another bullish run. LOL. Yes, no one can really predict the price whether to go up or down, so we need to be prepared as well. But as we can see with the price today, its very bullish, it can be a bubble but whatever happens in the future, the price will remain as good as it gets.
In my speculation bitcoin value as increasing value until December end and another raising up of value on 2018, so I suggest to all users that stay hold your bitcoin in your wallet. Because there's a lot of increasing of price will happen.
