Income from curation is about 10% per year, which is a good income. Income from HBD rates 20%. The most important thing is to diversify your assets at a good HIVE price. The time will come to sell HIVE for HBD. And the time will come to sell HBD (and buy Hive). Done right, it will be good for your personal account and the Hive ecosystem.
HBD is better, but it doesn't (shouldn't) benefit that much from market movement.
Yes. At some point :)
