Congrats on being in position and taking advantage of the opportunity. I commend you for growing your influence on the blockchain when you can. Obviously my goals are aligned with yours so we both this move works out terrifically for you.
There are many ways to grow an account and you are using one of them. The SP you purchased will be leveraged to earn more. It will snowball for you.
How to make the most out of my SP is still something I'm trying to figure out. I refuse to delegate to bidbots, or to sell delegations- which would moneywise be the smartest thing to do. Instead, I'm looking for ways to make the most out of my SP. Delegating to applications like Steemhunt, Actifit and Cleanplanet is for as far as I know the best way to grow my investment (next to the regular SteemIt activities, of course). Yet, I can't get rid of the feeling that I'm missing out on some profitable opportunities...
