There are really plenty of great ways to grow here on Hive. You could also start to play games :-). The best long term strategy is in my eyes engagement and I agree here with @russellstockley and @ph1102 especially when you do it in the ctp tribe.

When you engage not only will you develop relationships with others. There are also some authors that actually reward you for commenting on their posts. If you look at @jongolson, @ph1102 or @flaxz they almost always upvote or reward meaningful comments (There are others who do it, me included but our stakes are somewhat smaller).

Contrary to Hive, upvotes on CTP are actually paying author and curator for all size of wallets since there is not a minimal threshold that has to be reached (or I'm not aware of it).
