Book of Revelation of Jesus Christ, Tribulation, Interpreting a Youtube channel's theories

This is to mention a huge subject:  Prophecy and Interpretation of the scriptures, in order to make predictions.  

We have to know the times we are living through.  These are the days which the prophets in ancient times did speak about, our world is what they alluded to!   Many people who are Christian-oriented, continually turn to so-called "Revelations", which is actually, the Book of Revelation of Jesus Christ given to John on the Island of Patmos.  This is the "go-to" reference, this is the primary source for their current mindset.  The earlier source which was used by Revelation itself, are the books of the Old Testament.  So any proper analysis is going to have to include: Book of Daniel, Isaiah, Ezekiel, etc., along with Revelation.  

There are different camps of thinking and interpretation.  These include the categories known as: Dispensationism, Tribulationism, Rapture, and various others. 

As you can see by looking at these screenshots from the YouTube video being used as an example herein... 

In these End Times, there is an "unending" fascination with the predictions based upon "Revelation", that most famous and popular book from the Holy Bible.  Over the past decade I've known of this YouTube channel which has always offered their theories on the subject.  Not only theory, but it includes predictions based upon the ancient scripture (which are themselves predictions).  Prophecy and what is the proper understanding of it all? 

Should we take a gander at the latest?  It is up for discussion... found on another YouTube video comment: In the last two hundred years, there has been a massive surge of "futurist" interpretations of Daniel 9--where the Antichrist signs a 7-year peace treaty, launching a Great Tribulation, which precedes the return of Christ.

Obviously in order for this theorist to develop all these predictions and all the arrangement in the timeline, there has to be much assumed.  Then based upon the initial assumption, more assumptions are piled on.  The biggest assumption: are we in the End Times?  The last generation before Judgement Day?  

Regardless of the many prophetic statements, Ahgamen gives an answer.  Yes we are in the End Times.  This is the very generation where the final phase will be realized and fulfilled.
