Of course some whales can singlehandedly fund a proposal. Some proposals are near the threshold.
You understand that if such a win-win backroom deal is possible, it makes the whole proposal system exploitable and useless? $50 per day is what the whales call 'APR' and they focus on maximizing it. If they can get $100 per day instead, they will.
My example simply proves that SPS's game theory is completely broken and advantages whales. I guess nobody understands this, so I'm talking to a wall.
I will never do a proposal on Hive because I don't want to work with crooks, even if they give me $1500 per day.
