The average person will be able to remember his or her bank account number, but for a Bitcoin wallet address this is significantly harder to do. These addresses contain around 30 characters, which can be both (case sensitive) letters or numbers. An easy way to remember or share wallet addresses is by using an address shortener. Address shorteners create a profile for a given address, making it much more accessible. For example, Digiconomist’s Bitoin wallet address 135sepdzmesmHVxAnp7twvN9cE1VgfHG7H was shortened to bit.co.in/digiconomist.
