What, in your opinion, are going to be the most relevant crypto related topics in the next 5-10 years?

I am interested and invested in crypto for like a year now and every day I get increasingly thrilled. My goal is to research as much as I can, to participate efficiently during the next years. But crypto is a wide field of complex systems and projects. And sometimes it’s hard to keep track on everything that is important about crypto as a topic itself. So what do you think will be still relevant in the future? Which topics are worth it to invest time and energy (and maybe money) and learn more about? Web 3.0? Metaverse? DEX? You name it. I am very interested in your opinions and expertise!
