You're not mining anything; you have no idea how mining works. They sold you an app where you waste your useless time watching dozens of ads to earn more mSats that took forever to reach the withdrawal limit of hundreds sats. The only alternative is to find as many idiots as possible willing to watch dozens of ads in the same hope, and then you'll earn a little more than them. Spend your time being more productive and getting paid in Bitcoin or converting what you earn.
