PIP-18: Polygon 2.0 Phase 0
....
The initiation of the upgrade from MATIC to POL;
The upgrade from MATIC to POL as the native (gas) token for Polygon PoS;
The upgrade from MATIC to POL as the staking token for Polygon PoS;
The launch of the Staking Layer and migration of Polygon public chains to leverage it.[...]
Now what about token holders in exchange and in there various wallet what do they do to ensure they don't have worthless coin with them, now already they had stirred up fear in the eyes of holders and those who already trading it on their various trading platform.
I think there should be a proper way to handle this than just entire changing their ticker to POL, where as other exchange delisting their MATIC, and i'm mean to say is there no professional way to handle this like not delist instead of rebranding and changing names where either every traders and holds receives automatic equivalents of what they are holding in their possession both in exchange and in their respective wallets. This is a good news but could stir up a huge dump in their coin since most the exchange delisting them.
