How can i get/swap my ora in case i ve sent it to darkhorse few months ago?
Already done for you. Nxter who is one of our treasurers sent the new currency to everyone who had transfered ORA to DH. It looks like your address does indeed have XOS (note it's a currency this time, not an asset).
Same with me but I don't see any XOS or other currency on my account on trade.secureae.com (where I sent the ORA from). I still have an "Unknown" type transaction from NXT-E26D-DMFT-N8XV-37PBS which didn't add anything to my balance. Is this it?
Nxter should then be able to help you out (remember to provide your NXT address).
