• What is GBTC?: GBTC is the Grayscale Bitcoin Trust, an investment vehicle that allows you to invest in Bitcoin through the stock market. It's not a stock but rather a trust that holds Bitcoin.
  
  Where is GBTC Traded?: GBTC is publicly traded and can be bought and sold on the OTCQX, an over-the-counter market.
  
  Retail Investors and GBTC: Yes, retail investors can trade GBTC. You don't need to go through Grayscale directly to buy it; it's available on several trading platforms.
  
  Grayscale and Real BTC: When you buy GBTC, Grayscale uses the money to purchase actual Bitcoin, effectively backing the trust with real assets.
  
  Confirming BTC Holdings: Grayscale is subject to periodic audits to verify their Bitcoin holdings, and they publish these reports, offering some level of transparency.
  
  GBTC to Spot BTC ETF: Transforming GBTC into a spot BTC ETF would be significant because ETFs come with a different set of regulatory approvals and would likely attract more institutional investors. Grayscale aims to convert to better align with these market demands.
