In general terms is about ownership, so called crypto currencies have owners (Eth = Vitalik's band, XRP = Ripple and its CEOs and employees, USDC = Centre and Circle, Cardano - Hoskinson, etc.) Bitcoin is a protocol , it is free and opensource under MIT license, runs public decentralized ledger. No one owns it, there is no CEO, there is no company. Bitcoin is a comodity like gold and wheat, the rest of "crypto" are securities no matter what they trying to tell you. BTC is a coin not a token like ADA. Hope that helps. Use your google-fu for more... :-)
