Many in the comments here either have no idea how smart contracts work or have never played these kind of DApps before and are skeptical to anything new.
Some may have read over the last part :
SteemBet is at pubic testing phase
Since we just launched, we would like to help us out by playing it and tell us any bugs you find! You can reach out to us in our Discord server.
With that said, amazing job on the launch guys. After tearing through it (testing/troubleshooting) and looking at what code is visible, the platform seems legit and ready to grow. #SteemBet truly displays how fast the #STEEM blockchain is and that's a huge plus. Roll out the road map, whitepaper and dividends successfully and skies the limit.
Looking forward to more from @steem-bet!
