How do you split when you are a wholecoiner ? (+ 1 BTC)

Hello guys,

I achieved this milestone end of February and I’m on the road for a 2nd one (last milestone would be 2.1 BTC before the next halving).

I am quite disturbed by the latest information from Ledger and the fact that we can recover our seed phrase. For those with more than one Bitcoin, how do you store them? Should I put 0.25 on Ledger, 0.25 on BitBox2 etc ?

I'm afraid that the threat comes from within (Ledger) despite my 24 words being very well secured.

Any opinions or advises ? Best,
