I wanted to send a transaction. I also have one pending transaction which was not confirmed yet although I rebroadcasted and promoted twice.
I got this message:
ERROR: PRIVATE KEY REUSE DETECTED!
You are attempting to sign a transaction with input that have an already been used. IOTA uses Winternitz one-time signature (W-OTS) scheme, due to it's `one-time` nature, the security of funds in an address decreases rapidly if you re-sign new transactions using the same key. Please wait for previous transaction to confirm, e.g. by promoting/reattaching, before sending another transaction.
Does it mean I can not send another transaction when an other one is pending?
