Gold is generally less volatile, so saying "$40mm in gold" would likely have some lasting significance. But in a month, that $40mm in Bitcoin could be worth $20mm or $60mm or something else entirely. Giving the actual value in BTC would let us know how much exactly.
96000 btc i believe was the figure being thrown around however I also saw 39000 btc at the every early stages and that is much closer to the $40million estimate given in OP.
