Yes. And to have 300steem parked in wallet, i guess one needs to have at least been a dolphin (1000sp or so). 😀 Because before it reaches that number, I would prefer powering up, and maybe when I reach 1000sp i would keep powering up.
Right now I have +20steems parked in my wallet, I'm planning on using them to finance a communal account activities, like rewarding 2 steemians under rep 50 every week. So yes, it's been a while since I do manual powering up.
