Here are all the #bitcoin seed words. Someone recently commented on this list claiming that it's rather short. So let's see how secure it is.
With this list, even the shortest seed phrases of only 12 words give a vast search area for a potential attacker, with 10^39 order of magnitude search space. While generating a seed phrase is relatively easy, the cryptographic algorithms needed to derive a private key from the phrase are resource-intensive. In addition, for each private key generated from a randomly generated seed phrase, an attacker would have to scan the blockchain to see if the wallet is funded. If they were to scan the blockchain in this manner, they would be rate-limited and detected long before they even had a chance of finding a valid seed phrase.
Even if they ran a full node (the only viable option), the demand for resources would be huge, and scaling the attack, they wouldn't be likely to be able to test more than 100k - 200k seed phrases per day.
Theoretically, however, if an attacker could somehow test 1 million phrases per second, in order to have a 50% chance of guessing the phrase of just one funded wallet (assuming there are 50 million funded wallets today), they would have to run the attack for 2.39 * 10^19 years (that is 23.9 quintillion years). And this is for 12-word seed phrases only!
In addition, some wallets allow for a passphrase (a so-called 25th seed word) which is chosen by a wallet's owner and an adds another level of security, making any attack an expensive and hopeless endeavor.
So rest easy, your bitcoin wallets are safe.
