What was the first thing you bought with your Bitcoin? Did you treat your loved ones to a classy restaurant? Or did you bought something for yourself? Bitcoin indeed is really helpful 
the first thing I bought is book. the book is about the translation of qur'an and the explanation. I was into bitcoin because I wanted to buy the book.
Don't tell me that you started to use bitcoins only to buy that book with it, you can easily buy it by using fiat currency or credit card, and if you still say that your main intention to use bitcoin was to buy only that book then that doesn't make any sense.
