hardware limitations?Any insights on this?since there are huge waiting times on mining hardware/chips,my understanding is that HUT won't be expanding it's hashrate much if at all for 2021.Again, my understanding is that BITFURY,who was kind of a partner and the supplier of the mining hardware to HUT,and owned 38% of hut shares, has been selling those shares after their relationship faltered.I heard that the reason was that he machines were't as efficiient as claimed and since that is such a critical factor for success,the relationship ended.That could prove to be a limiting factor since I believe their competitors have scooped up any available gear and have arrangements with those suppliers.Could be very tough to upgrade or expand in this market.
