That money you keep apart is exactly what Bitcoin has done for me. I have used that money to achieve a lot of things, add a skill to my career, and now thinking of a business. Privacy too is part of it, just like others have mentioned in this thread. I can make payments with it online without thinking of the limit on my ATM card because Bitcoin has no limit on where you can use it or when you can use it, and many more other things which I have been exposed to because of it.
