I bought some NVST tokens during their ICO, and now they refunded the money in BTC, and I can see them in https://xchain.io/.
Now I want to transfer these BTC’s to Counterparty wallet, so I logged into counterparty wallet and clicked on import from other address. Entered my Private key and it shows my BTC. Now when I click on sweep, i get an error after few minutes, that “Funds not sent due to failure”.
Can you please help resolve this problem?
