But if I watch a youtube video that is released TODAY, and the narrator says "x currency is going to rise/fall to x value by the end of this bull run", what is the time frame he is talking about? When is this bull run(whatever that is) supposed to end?
be careful because in this cryptocurrency market there are many people who use that word "bull run" only as a force of expression or a force to be optimistic and not in a really technical way as it should be. the conclusion you had is right, so just focus on having more knowledge about the market and technical and fundamental analysis. in the past there were even analysts who differed between them if the market was in the bull run or not.
As a beginner I've managed to figure out what the term bullish means, and it seems to apply to same term "bullish" when dealing with stock market trade. And through that I can deduce what "bull run" means.
truth
When I tried to google this, I only find information about a historic event that has nothing to do with cryptocurrency.
you will not be able to see it on google, but you can see it on the charts, for example if the price breaks the support that is at $29000 and falls below $28000 we would sell panic and the bull run would become a nightmare, this is a way to get to see, also if the price starts to fall steadily from $57000 easily you can see that it is reversing from high to low, imagine for example that this week the price would drop to $47000, next week it would drop to $39000, and then the next week it would drop below $29000, then we would probably be in the trend change
