Smoke.io also have the 50/50 model and to be honest it is okay. At first I was like what you won't be able to earn crytpos that way but guess what you can, and I found I earn more cryptos with the 50/50 payout than I do with a 75/25 payout. SO I highly suggest going with the flow and waiting and seeing, you all might find out that you are actually making more with a 50/50 payout. The people this will effect in a negative way will be the Whales and Dolphins, but not much.
