Hut 8 recently announced they were buying $100 million in bitcoin.
While that is nothing compared to what MSTR has been buying, it's not a small amount.
Added together with their other bitcoin holdings and their totals are now worth more than $1 billion.

This puts them as one of the largest holders of bitcoin and certainly one of the largest holders among the public miners.
