I tried to import/sweep a casascius on the ballet wallet app it didn't work for me. Exodus worked for me for the btc then I used coinomi to claim the forks
Yeah Coinomi I've found to be super easy and again it allows you to set the import/confirmation speed/fees. However I've also only ever used a Satori chip for my trials. I need to try this on some other items. Specifically Cas and BTCC as that's what I mainly hold. I'm a bit surprised that Ballet didn't work. Did you ever find out why it didn't work? What kind of errors you received etc...?
