It seems vDice.io & KIBO are trying the same thing. But, I doubt people will ever embrace decentralized gambling, just like decentralized bitcoin exchanges have never got traction.
Actually, vDice already is LIVE and working.
vDice is the only blockchain gambling game doing that on Ethereum.
People will NOT know it is decentralized. They will use it because it is safer and better.
Bitcoin and blockchain show the importance of decentralization.
Now it is time to extend to other industries.
Wherever we can take out the middle-man it is good.
This includes exchanges and gambling platforms.
vDice does that.
We have developed proofs with our oracle.
These have on-blockchain betting times down to around 5s already (on test-net). Release is set for end of year, after peer-review.
Next year, we will compete with centralized services for speed and efficiency.
Then we will have all the advantages of decentralization, with none of the drawbacks.
So, people will use it because it is better. And with vDice they won't have to know it's decentralized.
