Good luck in your project, but...don't do 100% power up. I understand why, but don't.
I send everything I earn to bittrex, then trade it back and forth to earn more. It's the only way I can earn enough to power up the amount I want in a short period of time, plus earn more to spend it on things I need. It might look like I'm just sending it away to spend it, but I'm not. Powering up is important. It's also not bad to spend it though. SBD was made to spend.
Yeah, you're absolutely right. Might do the same as well.
