Tom Lee, chairman of BitMine Immersion Technologies, said this week could be a key upside opportunity for Bitcoin, arguing that long-term returns are concentrated in a small number of strong up days. In an Aug. 21 post on X, Lee wrote that most of Bitcoin’s gains tend to come during the 10 best trading days of the year and that this week could be one of them, warning that missing those sessions can sharply reduce investment returns. He urged long-term investors to stay consistently exposed through a buy-and-hold approach rather than trying to pick the exact bottom. Bitcoin is up more than 20% this week, putting it on track for its strongest weekly gain since 2024.
