Your pool didn't find a block for the past 60 days, with 1.5% fees on FPPS there must be a ton of reserves for the pool not to go broke, I honestly doubt this is going to work with your business model, have been you giving daily payouts for the past 60 days? also, how long can you move forward without hitting a block before closing, I do understand that it's a maximum risk of 24 hours of hashrate or so lost, but if I decide to use your pool I want some assurance that you are not going to shut-down.
