I have some strange problem with one my transaction. On 6 February, I send to my friend 5BTX. This is transaction ID: edc7a2d0032deedd45ab1ba80fa0bbbdb9b0adc12b5a9d58bfc6665a30180961
I have -5 BTX from my wallet balance. But when I check the airdrop registration page with my wallet, I have -12.12705043 (5BTX+7.12705043). I never sent these 7.12...BTX. Any help for this strange situation?
Use coin control to check your wallet, I believe the balance is in some "change" address.
