Re: [ANN][ICO] 📱 AppCoins - The New Blockchain-Based Protocol For The App Stores 🔋
There's one thing that I don't understand. You claim this coin is a circular economy. But what is stopping developers from withdrawing the coins 
Not sure if I understand your question. Any one can always convert AppCoins to a different token or currency, since its an ERC20 token.
However, developers have a incentive to reinvest a lot of their earnings from in-app purchases, which in turn will be partially distributed to users to subsidize more purchases. This is the circular part. All is explained in depth in the crowdsale appendix.
Where can I find the crowdsale? Would like to have a look and read more in depth about this.
