It isnt a secret that bitcoin is expected to go down still this year. A lot of traders that follow the price have predicted for months that it still hasn't hit bottom.

Goldman doesn't have some insider information unless it's about robbing taxpayers to cover their gambling and cheating.

As Neurotic Fish pointed out, Goldman Sachs is not to be trusted, since it took part in money laundering. I would say financial institutions as such are not to be trusted these days after they laundered more than the total crypto market capitalization and dare to say that it's cryptos that are not preventing fraud (since I know it sounds unbelievable, here's a link: https://www.forbes.com/sites/francescoppola/2018/09/30/the-banks-that-helped-danske-bank-estonia-launder-russian-money/#797136473197). Goldman Sachs is saying bad stuff about cryptos and then some news about them investing into a crypto startup, Novogratz hires a Goldman executive. Some say they are trying to spread FUD to buy low, and it doesn't look ungrounded.

maybe everyone has their own views about the future of bitcoin, but I still believe and are optimistic that the price of bitcoin will be able to travel even higher and at a better price.

these days everyone who has been trading bitcoin is getting anxious and most of them are getting desperate because their money is locked in orders that are never being filled because of bitcion's stability. so they end up trying to FUD bitcoin into some action.
the Goldman Sachs case here is a good case of that FUD of some idiot trying desperately to get his orders which they placed at about 5-10% below market value, filled. don't read too much into these things!

this is not just about Goldman Sachs and it is not about their fraudulent activities. they might have been the most honest group in the world and still their speculation would have been the same.
the thing is, whenever you read some speculation like this which is mostly nonsense, you have to think about why they are bothering with releasing something like this. the answer is that all those who ever speculate about bitcoin like this want to make profit from their speculation! in this case they want to buy bitcoin cheap. not so long ago in 2017 they were publishing the exact opposite of current speculation and were talking about how great bitcoin is and how it will be worth A LOT more than what it was worth back then in the long run! why? because back then they were trying to sell their bitcoins at a higher price.

Yes we do and before Goldman Sachs is one of the very bullish people on bitcoin but now he's changing his views regarding it.

This type of views are very popular now due to them having their own interest to bitcoin. I'm not sure if they are telling this just to drive the price down since last year there are some predictors who have been doing this and on the latter part it will be reported that they bought during the dip.

Why would anyone believe a company who focuses on helping the enemy to profit i.e. making banks richers? Stick with bitcoin, history shows it will always go up

Behind the scenes of Wall Street, many say that now bitcoin is being purchased by large funds. Bitcoin purchases take place outside cryptocurrency exchanges, so the rate of Bitcoin does not grow 

These are regular bankers who want nothing but their assets leveraged and get the maximum amount of attention for profit, why would I believe in them? They had been telling the same old, recycled scare-mongering shit about bitcoin ever since the ATH of 2013 blew-off. They were right for a short amount of time, only for bitcoin to go accelerating in 2016 and 2017. As usual, the first year after the ATH blew off, we will experience such cases of stagnant prices and lack of bullish movement since everyone has had their pockets full and are getting that money somewhere else. It's an obvious scenario, and I don't think that Goldman Sachs is a prophet by saying that there wouldn't be any recovery in the short-term future.
