Hello,
I saw that the founders of Samourai Wallets were arrested and that the website to download the wallet was frozen. I guess this has made users of this wallet unsecured.
Do you think this can happen to other software wallets ? Especially Electrum ?
You can always extract your seed words/private keys from electrum and use them in some other wallet software. If electrum devs get arrested tomorrow, you won't affected in a major way. You'll have to find another wallet software and there are plenty. However, electrum is still the best light crypto wallet software imo and without a doubt it will be a big loss for the crypto community.
But these are very theoretical events. Electrum isn't mixing coins or providing other privacy tools like coinjoin so nothing will happen to its devs.
