Hmm, a "convert to BTC" button on front ends would be super powerful.
The option to have a post payout automatically converted to BTC even more powerful. Hive will be the decentralized social network that pays creators BTC WITHOUT the need for users to fork out any BTC from their own wallets.
Actually, Hive already IS that, it's just that it takes a couple of extra steps and isn't talked about much.
Converting HIVE to BTC then paying out in BTC could be one option we will for sure take a look at.
