My way of saving bitcoin or money is splitting it into two, one half is for my savings for my future plans and whatever happens I will not spend it and the other half is for my daily needs. Yes there are many trendy things I want to buy but I prevent myself from buying it I always think that there are more important things than that. It's hard for someone to change the way the spend their money but if you have a goal in life and dream to have a better future you will surely think twice where your money will go.
The best thing to do for saving money is dont buy if this is not needed for you and buy that needs every day like foods and every you have extra money you keep the 20% of your money so that you can save your money..
