They have mentioned some specific times and only in those times they will contribute the 20% house edge revenue to the fund. I gave the suggestion before that why cant they make it flat and they contribute 20% for all the house edge revenue till certain date.
Fair point. I agree that those few hours won't be able to cater to everyone especially for those working or sleeping.
I suggest also freebitco could create like a button where every member could donate any amount (automatic debt from member balance), then the total amount would be donate for this institution in a separate btc wallet address.
I think this is a good idea as a lot of people will most likely want to donate without playing the multiply BTC. I know I would prefer to not play and just donate to the cause as we can sometimes lose more then what we are willing to donate so I think this is a great idea if the owner can add a donate button on the site.
