Hey @leviet7490. There are many ways to earn Hive. Some of them are regular posting, participating in contests and giveaways (check #contest and #giveaway tags), playing games built upon Hive like @splinterlands and more.
This is a slow proccess though. The best way to go is to buy some Hive, stake them (convert them to Hive Power) so you can have more influence on the platform and then start upvoting and commenting on posts you enjoyed!
Hive is a social blockchain so communicating with other users is a must if you want to be successful in here!
Cheers man, hope I helped.
