I doubt very much that you can back up what you say. In a recent interview he was asked how many bitcoins he owns as of today and he replied "at least that much", referring to the 2020 figure. We can't know for sure if he has continued to accumulate personally but I would bet that, if he has bought more, they have not been very large purchases, as those bitcoins as of today are worth $1.6B, more than enough to live on, and focusing on his strategy in MSTR the stocks he owns are more profitable to him in that almost every week they have more exposure to bitcoin.
