First of all congratulations on hitting the 10k SP milestone! I remember playing Steemgar with you a long time ago, when steemgar was still a thing.
Here is a screenshot for binance with one of my withdraws from there into my steemit account:
And I think the amount of SP I currently own should be enough to prove that I used it to power up lol (Unfortunately my post rewards aren't big enough yet, but I'm getting there).
If you still want me to post some proof of the power up I can find it for you...
Let me know if this is enough to be part of your contest.
Keep up the good work, hope to see you break the 100K milestone someday!
Thanks for commenting and also for your kind words!!
Could you plz reread the edited version? I made a clarification:)
