There’s a growing belief the crypto market (in more recent years) follows a pattern of rising and falling in price every four years. Whether this is the result of a self-fulfilling prophecy or not is difficult to say, however, many tie this theory to the timing of Bitcoin halving events, which occur roughly every four years (more specifically, every 210,000 blocks). This changes the dynamic of the market and ushers in a new market cycle – or so the story goes.
