Coin Delisting from any exchange? :- Do Good and cast it into the river

When i was new @cryto world
When i was learning about it that how to do tread where i should take entry and exit

I had bought some coin which are looking to give some decent profit

I bought and hold sudden market crash and coin gone in deep
my hold becomes long

One day i got email in my inbox that exchange delisting some coin
I do not know what to do
That time i am not having knowledge about crypto wallet
Mine portfolio left only one forth

Delisting coin from any exchange ultimately become portfolio sucker forcefully
We can not sell them

May be their are serval ways (like :- ofline wallet cold wallet etc. ) to make safe portfolio but these are the second things but the profit we make we lost it to pay their fees (wallet)

There should be more ways to bring real fund to portfolio which we have spent buying these funking coin
