I'd want to wait and watch to see if the price falls before buying that much. I'm currently staking a couple thousand. I get a pay out in 3 days - now I understand why people are pumping this coin. The turn around time to get a staking reward is much lower than with something like Stratis(close to 7000 days, granted I've only got like 4 Stratis tokens, I'm sure I'd have better return if I had more tokens) or Bitbean(69 days).
As far as Staking PIEcoin goes - it's cheap, has a quick return on staking and it's oriented towards being used as a currency. I hope no one buys it because it's still so affordable, so yeah we should build a master node. We could also just rent a VPS and save on electricity...
