If you buy on coinbase then you can send your coins to your exodus or atomic addresses.

This is a steep learning curve and intimidating! You might as well get started if you haven't been moving crypto around up til now.

You need to read the tutorials at coinbase and for each wallet.

When you click on your asset it will give you an option to

send or receive

so you would "send" from coinbase

and "receive" in your wallet

You click receive in your wallet and it displays your address for that particular asset.

you click the button to copy that address, then go to that asset in coinbase and paste it into the place where it asks where you want to send it.

For XRP and XLM going to your exodus or atomic wallet, it will ask, do you want to include a tag? You don't need to for that particular transaction but you might need it if you were sending to a person or something, I don't know.

ONLY SEND A LITTLE AT A TIME. Double check to make sure the address you pasted is the same as the address in your destination wallet.
