Is it better to split your btc into multiple addresses in the rare case one gets hacked?
Also, if one of your addresses did get hacked and all your other addresses were associated by having been generated from same seed, are your other addresses at risk (assumming they did not figure our your seed of course).
Do you feel it is foolish to keep too much btc in any one address?
Thanks.
If the addresses belong to different wallets, maybe. Best protection is cold wallets, no computer no hacking. The private key (seed words) is what you need to protect the most. You can put that in a paper written by hand, and another copy of that paper written by hand store them in two separate secure physical places.
If you want to do it with more than one wallet that is ok, but it doesn't improve security much unless those wallets are stored in different places, but then you'll have the overhead of protecting so many places...
