Of the total 433.6K HP I have, 122.8K are from writing and curation (35.5K author and 87.3K curation.
I have never sold any HIVE. After the fork from Steem, I sold my Steems and bought HIVE instead, nearly doubling my stash.
I put the HBD I get from writing and curation in the savings account.
Yep, a similar story to me although I don't have quite as much held as you or delegate in the same percentage of my stake that you do. I just keep powering up, posting and commenting (which is the fun part) and the future will take care of itself I think.
