This is what I like about @charlieshrem , he is contributing to the platform like all regular users.
Then again, if he keeps posting the same way he does, I don't think that powering down is much of an issue as he would make so much more per week considering the amount he gets to divest once a week. So he could power down as well if he wanted those extra Steem, but if you want to be more effective on Steemit with curation its obviously better to have more SP.
One thing you seem to miss in ypur equation is the fact that
SteemDollar pay interest
... currently at a 10% apr. Arguable, a steemdollar doesnt trade en par with the usd just now but if you believe the mechanics behind SD are sound you may want to diversify not into altcoins but keep some liquidity in SteemDollar .. (not actual investment advice)
Good point!
hmm, hadn't considered that either.
@charlieshrem, I'd say keep the power, for as long as you can.
Eventually you'll - I think very likely - be happy you did. And in the mean time, your voting power is a good thing for the rest of us.
But if you're only voting up on the few people you follow however, consider following more folks who create content you enjoy. Otherwise you're just keeping it in the family, as it were.
You spread more than a given monetary value with you upvotes, you spread good will. Far more important.
