You can only be profitable from Bitcoin if you hold it for a long period of time, at least 4 to 10 years. Within this 4 to 10-year period, you can experience one or two cycles of Bitcoin because Bitcoin halving always happens every four years. After each halving, we usually experience a bull run, a period when Bitcoin’s price pumps.
Bitcoin bull run can start after a Bitcoin halving or before a Bitcoin halving. In Bitcoin history since 2009 so far, most market cycles and bull runs start after Bitcoin halvings but there is an exception, this market cycle and this bull run began before a Bitcoin halving in 2024. It is a first ever time in Bitcoin history, we witnessed Bitcoin began its bull run and made a new all time high before a Bitcoin halving.
