i don't know what could be your reason why you need to use bitcoin but i have my own reason why, first I can manage my own money while it is stored in my wallet it is like you are also managing your own bank and you never have to worry because you are the only one who holds it, second you are away from the corrupt government and high taxes imposed by these corrupt and also bitcoin is much easier to use in some transactions, and lastly I can make profit even I am just holding it.
