It's important to remember the pool software is open for anyone to run a pool. And how many pools do we have? Two, the Dev's original and a secondary pool at MinersofMen.com Running a pool, if it is as profitable as you allude, would be a far better investment than Sanctuaries, but somehow we have 72 Sanctuaries and only, oh yeah, TWO pools. So either everyone here is brain dead (in which case, you're wasting your time to educate us) or pools are NOT so lucrative.
Sorry, Comparison of running a Pool or a Masternode is imo like Apples and Pears.
My (technical)view of running a Sanctuary is thats nearly equal to run a Wallet/Miner via Commandline on a vultr Box.
For the Pool you need a Windows Server reachable from the Internet. imo a security Nightmare.
