I prefer doing both investing some of my money in bitcoin and let it grown for 5 years or so and save money for daily needs and emergency purposes.
That's the right thing to do as you need to have good balance between both of them to have a smooth life ahead as you cannot invest all the money without saving few of them for future so even if your investment goes wrong your savings will take goo care of you and even in tough times you don't have to borrow money from your friends or family if you have saved regularly.
