Bitcoin is deflationary because a fixed amount of currency is inherently deflationary. Deflation is caused by there being a decrease in currency relative to economic activity. So if economic activity increases and the supply of currency remains the same, you have deflation.
A simple (and grossly simplified) example. There are 10 people with 10 dollars each and 10 apple sellers with 10 pounds of apples. If the apple sellers set their price at $1 per pound the buyers can buy all the apples at $1 per pound. The next year the amount of currency hasn't increased. There are 10 people with 10 dollars each. But the apple producers all doubled their production so they each have 20 pounds of apples to sell. To sell all of them, they need to set the price at $.50 per pound. That is deflation even though the supply of currency has remained static.
Economists fear deflation more than inflation because the inevitable result of that deflationary condition is a downward spiral in economic activity. There is less advantage in investing since future prices will be lower and there is an advantage to waiting since the cost of investment will decline in the future. There is an advantage in not buying things now because they will be cheaper in the future.(The apple buyers decide to wait a year since the ten dollars they save now will buy twice as many apples next year.)
