then I don't really understand what I can do with EQBs bought during ICO (as they would not be signed as I understood) except selling at exchanges.
or is there a possibility to turn my ICO EQBs into signed ones.
what would be the workflow of turning my blank EQBs into signed (and dividend paying) EQBs?
short feedback is very appreciated, thanks
EQBs bought during the ICO are used for transaction fees and to create issuances, regarding your question - yes you can turn your ICO EQBs into signed ones.
You'll be able to do this in the Equibit Web Portfolio where you can manage your EQB's and create issuances.
