Well this is a great strategy until greed kicks in when you see price pumping and then you buy the top only for it to dump on you lol. Just a personal experience as a noob. These days I just buy when I see a long red bar close to a strong support zone and go on YouTube to watch videos of people screaming it'll do further, that way I know I'm right. Always do the opposite of what the herd says, analysts, youtubers, bloggers they all don't know anything about manipulation, that's why they keep getting it wrong.
One of the first lessons that you are going to learn if you read a book about investing or trading is to never buy at the top, it is extremely tempting because people think that the price is going to keep going up and that they're going to obtain some easy profits, but that is not really the moment to buy that is the moment to sell, and if you have not bought bitcoin at that point it is better to let the market run its course and wait until there is a significant drop in the price otherwise you're going to be the one holding the bag when that drop happens losing so much money in the process that it could take you months or years to recover.
