Bitcoin mining company Riot increased its stake in Bitfarms by approximately 10.2 million shares in July to advance its acquisition plans

Bitcoin miner Riot continues to try to buy rival Bitfarms, with the company buying about 10.2 million more shares of Bitfarms stock in July, according to a filing on Wednesday.
In May, Riot tried to buy Bitfarms for about $950 million, and the CEO of Riot Platforms criticized Bitfarms' plan to block the acquisition. In June, Bitfarms took its first “poison pill” measure to prevent a possible takeover, and later upgraded that approach in July.
Riot shares closed down 1.74 percent on Wednesday on the Nasdaq, while Bitfarms shares closed up 4.03 percent, according to Google Finance. So far this year, Riot's shares have fallen 33.87 percent. (The Block)
