To be honest, there is no way to predict the accurate price of Bitcoin in the future. However, there are some analysis methods like technical analysis and fundamental analysis. Basically, it allows us to predict the possible trends that might take place in the market. It is not a sure fire way but there is some scientific background for it and hence it is reliable up to some extent.

At least OP asking here to figure out that video trustable or not because this is necessary to avoid misleading video which can make people confuse and trapped however bitcoin is unpredictable and there is no people can able to predict upcoming price for bitcoin  even if they able to do that i think they will keep it for theirself because they can took an advantages from that

I don't know about worthiness of those predictions because at the same time we had some economist expert who would say that bitcoin will reach the point of $50,000 till the end of the year 2018...

You shouldn't just believe on what other people say on what will happen to the price of Bitcoin in a few days or months, because even experts in this field can't accurately predict the price of Bitcoin. Some will just pretend to know what will happen and announce it in public to manipulate the price or to bring fear to other people, drop in price down to $2500 is obviously not going to happen, unless big problems will happen. This are all just smart guesses but no one can really predict the price because cryptocurrency is speculative investment, so do your own speculation, if you think Bitcoin will drop on that level then cash out all of it.

2500 real value, just don't think it will keep long, maybe it will be a quick rebound

I think that even if they call themselves experts in this field, I still don't care to hear any negative opinions about btc. I just do my own analysis and monitor the actual events happening in the crypto market since I believe that you should have your own gut feel and not just rely to some they called experts in crypto currency.

We can't just rely on this since this is just a speculation like others like this. We can't know for sure since the market is very unpredictable.

In fact, large investors manipulate the market for their own purposes. Many tried to predict the price. But in a small period of time, all the predictions are wrong. It is true that the bitcoin price will grow, but how much and when, nobody knows.

we are all aware of the investment risk with bitcoin is the price can not be determined whoever may only be analyzed from the previous development if it can be manipulated I guess it must have a purpose for investors who manipulate the prices
