1. Don’t use Bitcoin to fund your retirement!
2. Make sure that your computer system is up to snuff security-wise, otherwise your Bitcoin can be stolen.
Bitcoin uses cryptography to keep its online currency secure.
3. You also need to remember your address, otherwise you might not be able to prove that you own the Bitcoin.
Other than these three rules Bitcoin is a lot like your bank account. But it does have a fee whenever you buy or sell Bitcoin. Which is similar to receiving a deposit or making a payment.
As an investment it is quite volatile, so don’t make a large investment that you are not willing to lose. Invest a little, play with it a little, and see if it interests you. As with any investment you can make some money and you can lose some money.
