Since you have many questions, I would break down my answers! 😀

1. To get more followers (and supporters) and earnings, you should make quality posts (anywhere on Hive) regularly.
2. To cashout your earnings, you should first go to your #PeakD wallet at https://peakd.com/@rosewawa/wallet and claim your earnings. After that, you can withdraw your HIVE or HBD earnings on #BlockTrades (https://blocktrades.us). Those pages have enough information to guide you without anyone having to explain it in most cases.

Hope this helps! 😁
