You are certainly very right! But if bitcoin is low in value, it won't be as successful as it is now, and it won't have that value. All the hype is raised by those who are very beneficial to the rise in the price of bitcoin. This means that they have a lot of coins and they earn even more.
this depends, big whales can make fack value and manipulate the market for years till they get all their money out of such investment safely or at least with low loses.
we will never have a solid understanding of what is going on by reading the news and watching bitcoin going up and down daily.
better to trade based on hope and pray it will go up and you are lucky enough to win some few bucks, as much as hard work you are going to do still going to have less than 1% of the enough/needed understanding of the whole world news that can affect the market
