You are free to vote as much as you like. Only whales (investors) should be concerned about their voting power really but unfortunately when these changes happen everybody assumes it affects them too.
I wrote this post to try to help those people who are reducing their votes out of fear and show them there's nothing to worry about. My power is 65% now and so my voting slider is coming down again. I don't know where it will settle but I expect it won't go near 20% after I experimented with that account in the video. You can see that it takes a lot of votes to actually get that low because 100% votes only reduce 2% of what's left, which at 50% becomes 1%.
