You don’t need a whole bitcoin!

People get freaked out when they hear that the price of a bitcoin is several hundreds or thousands of dollars. Let me put you at ease by letting you know that most bitcoin exchanges are made in decimals. There is a value of Bitcoin know as a Satoshi which is valued at 0.00000001฿. People trade in Satoshi all the time. 1 Satoshi is worth, roughly, nothing. You would need 0.00001฿ to start registering in US currency at about $0.02. The idea here is that Bitcoin is designed to be very valuable while still being useful. You can buy something that costs $10 USD by exchanging 0.00409฿ the system is designed that way.
