how can someone block your wallet if you actually have your keys, can't you import them into Electrum for instance?
Yes, You can import your seed phrase into any other wallet supporting BIP39 seed phrase and access your fund.
I have read many reports regarding blocking accounts on blockchain.com. But they all are related to their trading account and they have nothing to do with blockchain.com wallet.
I see, I wouldn't use their trading platform either, there are much better options, safer, more established and trusted ones. There are so many exchanges nowadays, that I can't find a single reason to use their service, to be honest, I didn't even know that they operated as an exchange. I'd appreciate if someone could answer if they also offered it in the past, since I've only used their wallet.
