Hive account@breakaway-dev needs to note and address the issue with your lead image. its strange that it doesn't show for you but it shows for others.

BTC rewards go to your lightning wallet instantly, once certain accounts vote. for example, this blog got votes and should have some sats: https://hivehub.dev/tx/2cbf1a35eadd79ede47787506efbdd252eb53d01

The rest of your rewards come as standard hive rewards and can be claimed in most wallets 7 days after the post is issued

amount of BTC in your Xverse wallet only affects which feed you can post in. if you have a lot of BTC, you can post in feeds with bigger BTC holders
