The best time to buy with me is non-existent, it's simply about what profit you expect to earn.
Researching the market from the outset to predict future prices is only relative because really things happen a lot of surprises.
I have since bought BTC at fairly high prices and considered DCA long-term, only when the profits start to increase is the investment comfortable. And such investment lessons will help us to know temporary losses, because sooner or later we all have profits.
