Microstratey, the fourth largest owner of Bitcoin (BTC), did not buy any new tokens last week, announced performer Michael Saylor at X, where he ended a 12-week series of purchases.

Since November 11, Tyson’s Corner, Virginia-based company, has purchased 218,887 Bitcoin, according to Saylor. It currently has 471,107 Bitcoin.

While Saylor did not say why the company was holding back, a probable reason could be its impending earnings after the market close on February 5, James Van Straten said a senior analyst at Coindesk.

Public companies are entering a so-called blackout period for some time before earning messages to prevent insider trading. During this period, there may be days, weeks or even months, people with financial information about the company are limited to buying or selling the company’s securities.

In Microstratey’s case, given that most of its balance is Bitcoin, this may include trade in cryptocurrency.

Last week, the company announced a preferred stock offer of approx. $ 250 million to buy even more BTC. Just a few days later, it doubled more than that amount when it sold approx. 7.3 million shares in the series.
