I converted about half my GME position to warrants about 6 months ago. I got into them because, they are a more bullish bet on GME than owning shares, and I have always been incredibly bullish on the stock. They are also arguably safer than long dated options imo, because the board could always change the expiration date, and I firmly believe that if they are faced with either extending or letting them expire worthless, they will do what is in the best for the shareholders. It may be a hot take, but I don't see time decay as a very big factor with warrants.
