As it grew in popularity, Bitcoin became cumbersome, slow, and expensive to use. It takes about 10 minutes to validate most transactions using the cryptocurrency and the transaction fee has been at a median of about $20 this year. Bitcoin’s unstable value has also made it an unviable medium of exchange. It is as though your $10 bill could buy you a beer on one day and a bottle of fine wine on another.
