Let’s say I want to enter into a bet with my friend that if it rains 10 days from now, I will pay him $100. If it doesn’t, he will pay me $100.
Would it be possible to take advantage of smart contract on Ethereum to do automatic payout to the winner of the bet? One idea is to have each of us deposit $100 worth of ether into the contract and at the end of 10 days have the contract automatically send the contract balance to the winner upon consulting an external oracle for weather information.
The question is: at the end of 10days if ether depreciated, how can the winner of the bet get $200 from the contract, thereby netting $100 himself from winning the bet.
I want to see if it's possible to model a bet using smart contract but it seems if the underlying crypto currency depreciates, the bet agreement could not be honored
