I’ve been doing this when I started purchasing bitcoin. I never go to bars more often, I minimized my gambling activities, and I stop buying my dream gadgets so I can save a lot to invest in bitcoin. But later on I realized, that there is still no guarantees that I will be highly profitable with bitcoin in the end knowing it’s price would suddenly moves up and down. So what I do now is just to invest on my spare money. I can still enjoy my extra money with some of my wants, and at the same time invest in bitcoin without setting a fixed target when to sell.
Denying some kind of lifestyle to invest in bitcoin is not a bad decision, for people really understand what bitcoin is for them to have the courage to deny themselves of pleasures they know what they will gain from bitcoin in the future by investing in it. The main target is to increase financially and not to spend money on things that can not help you to grow financially. Investing will always be my first decision because know the value it will later bring me.
