We received several requests proposing us to always wait for payments to be confirmed after the end of the round. What do you think about the idea to introduce some specified interval (1 hour?) after the end of each round? If the payment is received before the end of the round and confirmed within this additional interval, then it could be counted. Winners would be able to be announced after that.
The truth is that sometimes players have no control over whether their transaction will be confirmed in the next block or in the next after next... (their wallet can generate some strange transaction with lower priority...)
No no no. That would take out all the fun
I think you should take some fee for not confirmed.
Maybe not full fee but maybe 0.5% or something.
