Going all in on cryptocurrency (Bitcoin, and others) is a good ideal. The path to it is not as straight forward. The traditional systems are designed to lock you in. For example, amy large purchase (house, car, etc) is likely goinh through a conversion to fiat because most sellers don't accept cryptocurrency. Your child's college would probably require fiat for fee payment. Given, how volatile the fiat vs cryptocurrency market is, it will keep aa significant population away from converting their life savings.
