Regarding blockchain wallets, we saw many complaints against them a few months ago. I am not sure if there is still some issue, like previously when the user's wallet was empty from a non-custodial wallet. There were some stories about how Blockchain staff were involved with this shady hack. Somehow they had gotten the recovery phase through email hacking, so through the file, their wallet could be drained. I will advise you to use a hardware wallet to secure your funds. Don't always think cheap; think about securing your funds.
