May 10, 2026 (The Australian - ABIX via COMTEX) -- Data centre company Iren was called Iris Energy and operated as a bitcoin miner when it tried to list on the ASX in 2021, but the ASX knocked it back. That proved a blessing in disguise, as Iren instead floated on the tech-heavy Nasdaq exchange in the US, with co-founder Dan Roberts noting that on Friday it traded $US10bn in just that one session, which he says is more than the ASX's on-market dail turnover of $7.5bn.
