I mostly save up my bitcoin for future fun purpose. I have a day job which pays me well so I dont need any extra income to sustain my life. I am ok with my salary. But I also save up bitcoin from various sources like signature campaign or trading. It is because I want to make my dream come true.
Since long, I am planning to buy a superbike. I have not yet decided the model, but I need a superbike because I want to go for cross-country touring. My current bike is good for city commuting but not touring. So I want to buy a superbike in future. Definitely it is not a necessity but thats why I am saving up my bitcoin. Probably 2-3 years down the line, I would be able to make my dream come true.
