Well, I see a tremendous opportunity in Steem price now just as you do, thus, I've been selling my entire steemmonster collection and powering up(nothing to do with the game btw I just value the opportunity of Steem so much more at this price), dollar cost averaging and powering up, any spare money I got powering up, any tribe tokens I earn I convert to Steem and powering up. And, soooo much more.
Basically, I don't see any obstacle in my way to powering up Steem at this price. I guess I'm a huge believer of STEEM blockchain. ;)
You are not alone. Nowadays I am also Powering Up, but with very small amounts. Okay, I am not converting every tribe tokens that I earn to Steem, but I am still Powering Up.
Nowadays I am a minnow with currently (2019.09.14, 00:45 CEST) 646.193 Steem Power. Instead of buying Steem, I am trying to earn it by being active both as an author and as a curator.
