First of all, you don’t need to prove to your parents that Bitcoin is the best solution for all the world’s problems. Above all, you need to show to your parents that it’s not just another fleeting hobby of yours. So dedicate as much time and energy as you can, to learn about Bitcoin. Then you’ll find out to yourself that you’ll persevere with your passion for the long term or if you’ll simply be unnecessarily asking your parents for money. If so, they’ll notice it themselves😊
