my address doesnt change anymore after receiving different transactions.
Since you said "anymore": Did you, by any chance start using "Jaxx" after very long time?
For which coin?
- From its help section:
In Jaxx, all coins are HD; however, all Ethereum ERC-20 tokens are not.
PS. We have disabled HD for Ethereum as of Jaxx version 1.2.13 - More on this
here
If that's not your case, then your only option is to try what "TryNinja" suggested.
