I would neither save nor transfer. I would, undoubtedly, power up. The only reason I have a few STEEM stagnant in my wallet right now is that I am considering buying a Steem Monsters pack and am saving up while considering it. Even so, it's a pity that the packs are being sold at such a time in the market, for a starter pack costing $5 USD is A LOT of STEEM right now.
STEEM is a very valuable asset. Say what you will, and I'm not gonna sit here and pretend to be more knowledgeable on the topic than anyone else. I'm certainly not going to pretend that I have a crystal ball. But, I am a firm believer in the future of STEEM and can't wait for it's future. Maybe nothing will happen; regardless I'm in it for the long run.
My point is, I would use that 30 STEEM to power up. I try to power up every little last bit I can. I have never sold and I am very happy about that. I think if Steem does see mass adoption that the people with a good amount of SP are gonna hold a lot of power over vote distribution. That means attention. It also means being able to send out hundreds of votes to those deserving of it; and your friends and family if you so desire.
Again, I got no crystal ball. I am not giving financial advice. But I'm going to power up every last little bit I can. I'm hoping to make it to 500 SP by the end of the year. To most, that doesn't sound huge. But; it's progress. I like to see every last little bit as progress. Even the .001 curation rewards. I love thinking about it just accumulating in there, never being spent, just growing account power. It's also a mindset that allows me to be much more nihilistic about the ups and downs of the market. Amidst the craze of everyone running around with their hair on fire, I'm sitting back just tap tap tapping away.
If you meant transfer to VESTing then my apologies. I just realized that is what you could have meant, meaning I was incorrect in saying neither. Because I strongly believe that's what we should be doing. That's what I'll be doing, anyway. Cheers!
