Explaining Bitcoin to Grandma

Want to know more about Bitcoin but don't care about the geeky underpinnings?

Here are some differences between Bitcoin and the traditional US financial system:

  • Most users hold a small amount of spending money in a wallet and most of their money in an account. 
  • To create an account one needs to find a financial institution to supply the account, apply for the account, give them all kinds of personal details, fund a minimum deposit. 
  • Banks accounts pay interest for using account holder's money and charge fees for services. 

  • It is a best practice to hold a small amount of spending money in a "spending account" and large amounts of money in accounts created on machines not connected to the internet.
  • Accounts are created through software or using a service provider.
  • There are no minimum balances and no interest paid on account balances.
  • It is recommended when sending funds to include an optional fee. Today the recommended fee is around 6 cents.
Transaction History
  • A receipt is needed to provide documentation of payment between parties.
  • In financial institutions transactions are kept private, but may be provided to government entities (courts, regulators, law enforcement)

  • All transactions and account balances are publicly visible. However account holders are only known if they disclose their identity - such as submitting identifying information to an exchange or as part of a transaction.
  • Cash transactions are irreversible.
  • Most other types of transactions are reversible.

  • Transactions are irreversible but the other party may issue refunds.
Issued By

  • Computers solving mathematical puzzles.
  • The process is called mining. 
  • Today specialized hardware is needed to profitably mine Bitcoins.
Currency Limits
  • Governments can create as much currency as they want.
  • This devalues that government's existing currency.

  • 21 million Bitcoins. 
  • Bitcoin is created at a predictable rate and will stop being created around 2140.
Risk of Loss
  • When I've had fraudulent transactions on debit cards and credit cards they have been reversed no problem by my banks.
  • When I've had cash stolen I've never recovered any of it.
  • US depository funds are covered by the FDIC. Banks have bonds to cover losses.

  • Improper use of software can result in loss of funds.
  • Having a computer hacked can result in loss of funds.
  • Software bugs can result in loss of funds.
  • Institutions being hacked have resulted in loss of funds.
  • Computer destruction or theft can result in loss of funds.

  • To send money a great length of distance I need to use a third party or deliver it in person.
  • Taking amounts over $10,000 across the US border needs to be declared to FinCEN.

  • The difficulty of sending funds does not change with distance. Bitcoin can be delivered across the globe the same way Bitcoin is delivered to your neighbor.
