I always appreciate these people who manage to save money by making a lot of sacrifices. But I think first of all they should focus on their basic needs and then its okey to go ahead with rest of money. If anyone compromise with healthy issues or others major things in their life for money, then he or she will must have suffer in long runs if good to investment or money. Not don't ne so greedy, sometimes greediness could ruin a life rather then making anyone successful.
Exactly, the necessities of life are very important and must be a priority, but we also have to know that everything is done with sacrifice and must accept the bad risks that might occur. We must endure a life of luxury at a young age and still save the money we have always in Bitcoin and be able to enjoy the benefits in old age.
