There is a bull and bear market. In which market is it hypothetically possible to make more money? In which of these two markets do people usually make a profit? And how to determine the beginning and end of one of the markets?
You don't make money all the time, there are periods when you accumulate and there are periods when you dump. Bull period is a time when you wait to dump, bear period is a time when you're accumulating as much as you can (with the money you made after you dump at some high price). Let's be clear, we are talking about Bitcoin here, because Bitcoin always bounce back, unlike some other coins.
I wrote that more than once, you can't know when is the beginning and end of some period, it's why you never buy with all of your money, you never sell everything you have. What you do is trying to feel the period with your buy or sell orders, you don't place one order you place several, each higher or lower than previous one.
