I totally agree with you. Investing in Bitcoin or any other investment requires thinking about long term. People who want to make money quickly are mostly unhappy and worried about when to invest. But if you focus on growing your investment over time and can handle ups and downs of market then you don not need to worry about finding "perfect" time to invest. In the end it is very important to learn as much as you can set clear goals and make plan that fits with how long you can keep your money invested and how much risk you can handle.
