Official statement from website https://www.popultrade.com/Dear supporters,
We are herby informing You, that unfortunately we did not reach the Minimum Threshold set in our Crowdsale, due the suddenly raise in Ether value. The good news is that we gathered certain funds via FIAT payments, from investors. Thanks to their effort, and fresh ideas, we will create a new version of Popultrade that will be presented on this page soon.
All payments in Digital Assets (ETH) will be returned. To claim refund use Ethereum Wallet > Contracts > Watch Contract - enter address "0x5031563d2a62095c3f5a1236855f0ea3d1e3f29c" and use the claimRefund() function.
