Hello

started with Bitcoin about in year 2020 using BRD wallet app and never touched it again. Today I would like to recover my funds into
Electrum of Tails (no persitance) in order to make a donation to GraphneOS.

I will recover the funds into Electrum like shown here:

Question:
Since I am not going to donate the entire BTC funds to this foundation I am wondering what will happen with the rest if I am
going to shutdown Tails..

Are the non spent/donated funds lost this way? What precedure do you recomend?


Thank's a lot in advance,
