Does anyone have the exact numbers of how much protection you get using a 24 word seed vs using the conventional default standard that shows up automatically when you create a wallet in Electrum?
It's still not clear to me that you can trust this type of wallet, that could be bruteforced and then all of your keys are compromised forever as long as you keep creating them on that wallet. It still seems safer to use a wallet.dat file. I want to see the math.
Actually there is no problem with 12 word or 24 word seed (at least for now), therefore every assumption that is related with concerned that this is not safe has no real strongholds. The real problem is the way in which people kept that seed as backup, and therein lies the real danger.
For me my 24 words hardware wallet seed is something I consider pretty safe, although there are people who even consider HW as an unsafe way of storing cryptocurrency. Fortunately I'm not so paranoid, security is available to all of us - but it should be understood and applied.
