i will say it is smart & sober to break your Bitcoin in 14 wallets, it is another point.  El Salvador recently divided its 6274 BTC holdings into addresses with a 500 BTC cap each. Perhaps they are worried that the theoretically dangerous possibility of quantum computing will ever crack their public keys, hehe.  you know everyone could audit it using the public dashboard, while keeping key reuse risks in check.

you know  there is currently no quantum rig that could even crack a 3 bit key, so quantum threats are still very much theoretical.  i will say the actual master are Bitcoin dev who are preparing hardware & software updates in case that threat mysterious threat evolves, lol .  So yes, vest wisely but first have faith in Bitcoins adaptability.
