I once gave a seed in a WhatsApp message (as an image) to a friend .
It was a low amount, like 10 usd. I also gave the instructions on how to redeem using electrum. But he never redeemed it .... my idea was to teach him how to move bitcoins and learn, but he didn't
After a few years, I can still see the coins untouched
He probably forgot, and if the amount is not significant, he won't even bother.
In my case, I plan to write (on paper) the necessary instructions, because the amount will not be negligible. (I hope that at the time of use, it will be more significant.

)
As there is a possibility that I will not be present when these coins are used, the matter must be independent of me.
