RE:VolumeI believe that reddit post is a few weeks old now. I think it has more to do with the recent American bank failures. Some see it as good for gold, others are unwilling to keep their money in a risky bet.
The price has generally stayed in the same position, so it's not like people are gobbling up shares faster than they are being sold. I have to think if someone REALLY new something they would be willing to continue to buy up shares into the mid 40s. There are so few shares on the market, even if a few people maxed out their ability to invest it could greatly raise the share price.
