According to the source, Steak 'n Shake is promoting a Bitcoin Burger that includes actual BTC distributed through Fold, a Bitcoin rewards partner, as stated in the linked announcement. The source does not disclose promotion duration, unit limits, on-chain transfer method, or redemption mechanics, and it provides no sales or volume metrics to quantify market impact. For traders, this is a sentiment-positive merchant headline but lacks data for measurable BTC order flow or transaction analysis. Source: user-provided tweet linking to the announcement.
