I think luck might get you some whale upvotes once in a while, but it's not sustainable. The HIVE ecosystem is currently in its distribution phase, which means we're trying to spread the token far and wide. This sometimes means that good upvotes are handed out to mediocre content creators. As more and more Orcas are formed, however, the community is increasingly leaning towards higher quality content from creators with a proven track record.
Luck works a few times, but consistency will always be better in the long term.
