You don’t need to use the same lightning wallet to send and receive zaps. 

nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm is self-custodial meaning you have to open and manage your own lightning channels. They should have instructions on how to do that when you sign up. If you’re not ready for that yet, you can sign up for a custodial wallet that provides lightning addresses and set that lightning address on your profile. There are different options depending on where you’re located. I use Strike which is great, but there’s also no kyc options like nostr:npub1h2qfjpnxau9k7ja9qkf50043xfpfy8j5v60xsqryef64y44puwnq28w8ch. You can only zap others using Alby when using the Primal web app, but at least you’ll be able to receive zaps to your custodial wallet. 

If you want to go the easiest route, use the Primal mobile app which has a built in wallet.
