Same sector, same three years: $10,000 in Iren is worth $108,872 today, while the same bet on Marathon Digital sits at $11,854. Picking the right bitcoin miner mattered nearly 11x more than picking the trade.

A $10,000 position in Iren on October 9, 2023 grew to $108,872, while the identical stake in Marathon Digital reached just $11,854.

Iren returned roughly 10.89 times the original investment while Marathon managed 1.19 times, so the choice of which miner to own mattered almost as much as the decision to invest in the sector at all.

Both companies face the same bitcoin price cycles, post-halving dynamics, and shifts in network difficulty, which makes the divergence a story about company-level execution and positioning.

For investors sizing up the bitcoin-mining space today, this three-year split shows that sector exposure alone does not determine returns. Stock selection carried nearly the entire weight of performance.
