What problem did crypto solve for you?

Hi, there are a lot of projects that want to solve something in crypto, some of them are or could be really nice tools and other projects just want to artificialy create some problem and slap their solution on it. I know crypto world is still not fully developed, but what real life struggles did it help solve to you? I really want to hear your story cause there might be some amazing usecase outside of “not using bank”. I know about Cardano, that wants to focus their blockchain towards africa schools and goverment from my understanding, but that us still more of future concept than reality. Thank you for sharing your story.
