Toporek added, “We continue to rapidly scale our business with 2021 mining revenue of $10.9 million compared to less the $1 million in 2020. Our momentum continues according to plan and for the first quarter of 2022 we expect that our mining revenue will be 80% to 90% of what the full year’s revenue was for 2021.
