Are there any big fees for it? i have downloaded exodus wallet , but there are asking 12pharse words. but we only have private key. so what is that differnace?
Use Electrum wallet (electrum.org) instead. More options for importing wallets, and it's a better Bitcoin wallet altogether despite the old school UI.
Thanks for the explanations , everybody. Now i have understand. Anyway , Are there any alternative rather than Electrum wallet. Anything can happen in crypto. If electrum wallet hacked , then what else we can do?
As long as you have a good operating system you need not worry but rather be careful on certain adds or apps you're downloading into your device as they can pose danger to your keys by exposing it to hackers. I have been using electrum wallet for a very long time now and when compared to other wallets I'll always pick electrum ahead of others.
Conclusively keep your private keys safe it's very important than you know.
