Can I mine Kaspa directly to an online wallet?

Yes — you can mine Kaspa to an online wallet by pointing your mining software at that wallet's public address. A public address is the destination string you share with others so they can send you coins; mining software uses the same kind of address to know where to deposit your earned rewards. Because an online wallet already has a node running behind it, no additional node setup is required on your end. For a beginner who wants to try mining without a complicated technical setup, this means an online wallet is a valid and functional starting point.
