In my position using SP to generate Cashflow make the greatest sense.
However I was fortunate enough to stock up on SP before the massive bull-run we're currently in. Generating cashflow means I don't need to try to second guess what the market is going to do.
Any sideways or upwards movements in STEEM means good weekly returns if you have a decent amount of SP. If you enjoy posting and write well it's a no-brainer to hold on to your SP. Even if the Steem price drops, the returns are good. If Steem completely crashes, you have Bitcoin and/ or fiat to pick up cheap Steem with.
Ultimately, I don't want to spend my life trying to second-guess what the crypto-market is going to do. I'd like to earn doing something I enjoy and have a major say in how much I'm compensated (rather than having to rely on the whims of others). SP offers that.
Sidenote: I'd caution against greed. It's important to remember that any rewards allocated on the Steem network are subject to the implied consensus of the community. Systematically allocating disproportionate rewards to posts/ authors that offer little value can quickly backfire. It's inevitable that people will start to downvote those who take the piss. I think as long as you're prepared to offer value, rewarding others that offer value and not be a complete dick in the process, you're golden. Afterall, the best way to increase the long term value of your capital is to ensure Steem/ Steemit can continue to attract and retain quality content creators to the platform.
I completely agree with you. We are in a big game with a lot of diverging opinions about what is okay or not. I just try to not poke the bear too much.
