An ICO is going to start in a while. It only accepts transactions in bitcoin but not in ethereum.. please tell me which bitcoin wallet to use because i don't want to use exchange wallet due to security concerns.
I have blockchain wallet but its address changes after every single transactions. so i cant use the same address for later purposes in ico.
please guys let me know if you have any idea about a secure wallet like blockchain wallet. It would help me a lot.
PS: I don't want to use hardware wallet as of now like ledger nano s, trezor etc.
