I have to say also the 25 minutes who take maybe are a wrong calculation, because what if he was "lucky" to find the order on 25 minute, but you need to make more and more tries to find out the average time, not only one disorded seed.

Asides of that like a few guys says above, this its not related to BTC or cryptocoins, its all about basic maths and calcus, we know from a long time ago what time or how much tries do you need to solve that.

And obviusly a 24 words can be more safe in that case, but also, we can still go up, why not 36/48/72 etc. No sense

Its like a send a photo of one key of my house to a locksmith, well yes he can make a "fast" copy, and open my house......
