Tether, the stablecoin issuer, announced on Wednesday that it will begin buying bitcoin (BTC) for its stablecoin reserves using a portion of its revenues this month as part of a new investment strategy focused on the largest cryptocurrency by market capitalization. Tether stated that it will purchase BTC using up to 15% of its realised earnings from investments, excluding any unrealized price appreciation of its reserve assets, and will add the tokens to the reserve excess. According to the announcement, the corporation would keep the BTC stockpile on its own and will not use any third-party custodians.
