NEW: K33's Vetle Lunde argues Strategy's STRC preferred shares are an expensive way to stack Bitcoin.

He estimates STRC added $725 million to annual dividend costs, about 8,740 BTC, lifting preferred dividends from roughly $830 million to $1.56 billion in 2026.

Without leaning on STRC, he figures the company would still hold 843,303 BTC as of Oct. 12, only 4,947 short of the actual 848,250.
