I also have no problem with my bet as when I hit the button the contract was immediately signed will play later and post my experience again, the Playblock blockchain is new in the gaming industry it claimed to be fast and gas less.
I also did not have any problems after the approval. It didn't take time for me to sign the contract as well. One more thing I noticed today is that Bitwinup is Certik Audited already. I have been farming Certik airdrop lately, and when I visited Bitwinup today, I noticed it was audited by Certik already. We haven't seen their representative these days. Probably they are busy working on their platform. I don't know if Bitwipup want to establish them as a Casino or Just a trading platform. But as their ANN is in gambling section, I believe they claim to be a casino. What is the possibility of adding various games apart from trading? Is there any chance?
