There are not many words, 1625 is not much when you know the power of today's PCs. On my PC, with a Python script, I can test several billion possible combinations.

That's what I don't understand. If I test the combinations and find for example one that has funds, it's over for the portfolio, right?

It would be easy to take 12 random words from the list of 1625 words and test and then repeat and that several times per second.

Nope. Python is notoriously slow for loops and there are faster implementations out there. Depending on your type of loops or iterations, the actual rate will probably be far less than a couple of million per seconds.

There are actually tons of bottlenecks to be considered when you are bruteforcing seed phrases. First of all, you have to consider that various key stretching functions are used in the various steps of the process which slows it down significantly, because they are far more intensive than just generating random 12 word phrases. You are unlikely to really achieve speeds anywhere near feasible.

The other notable bottleneck is trying to find the addresses with any transaction history or funds. You have to get a set of all of the used addresses on the blockchain and search through it which involve both storage and computational complexity when you are searching thousands or billions of seeds per second.
