Bitcoin miner Bitfarms is adopting a "poison pill" strategy to prevent takeovers by peers and rival Riot Platforms. The dilution anti-takeover measures, also known as "poison pills", are understood to be measures taken to prevent companies from being unsolicited takeovers and attempts to reduce their attractiveness. Bitfarms said the plan, which has been approved by the board, "is designed to preserve the integrity of its previously announced strategic alternative review process and is in the best interests of shareholders". Previously, it was reported that Riot Platforms has acquired a 12% stake in Bitfarms in the past few weeks, in an attempt to build one of the largest bitcoin mining companies in the world.
