It wasn't a mistake. Many financial advisors recommend you pay off all debts because it frees your income to do so many things - you can survive with very little income now. Even if you lost ALL your money now in cryptocurrencies, your monthly obligations will be so low that even a job that pays close to minimum wage should be enough to survive on. Becoming debt free is a lifelong objective for many people that they never achieve.
