First mistake is to use Blockchain.com that is not open source which means your asset is not safe there. If you need reliable software wallets, Electrum is fine and should be considered. I had a Blockchain.com wallet but since I learnt that they are not open source, I have abandoned the wallet. Now they even require me to do KYC to be able to convert to fiat, I don't know what that is because I have moved on.
