Have you ever wondered if it is possible for someone to crack the seed in your wallet?
I’m not referring to someone being able to find where you keep it, but to find it mathematically.
Could a hacker, using brute force, decrypt your seed knowing your public address?
There are more and more wallets and that increases the possibility of randomly finding a wallet with funds, so could someone combine the words in such a way to find a seed from one of the many wallets that exist?
I published an article on this topic more than three years ago, and it is still relevant today:

Please read the article and you will see the remote (I said remote) possibility of that happening.
Multisig protocolhave another meaning, it is the control of funds from a single key for partnership reasons.
For greater security, you should use hardware wallets.
