Based on my research, I strongly disapprove of mnemonic-formed private keys (the seed words form the private key) because it substantially reduces the amount of private keys that hackers would have to target to guess a real/used address…
Although this may not be an issue at this time considering the amount of processing power it would take to guess private keys formed by mnemonics, but with exponentially increasing processing power, I am still concerned.
I would like 512 bit private keys and mnemonic free (random letter/number formed) to enhance security. Why is this not already being done?
