White-list (or WL in short) buyers are the first to buy units from an NFT collection.
The WL are usually investors and active users who participate in its communities (via dedicated Discard channels).
Each collection had its rolls, but usually, the more you get new users to know the collection (reach) by adding them to the Discard platform and sharing tweets about it, etc., the more likely for you tp get in WL.
Some of them also give free NFT from the collection.
BUT – check the rolls.
Each NFT collection is different.”The NFT token can’t be copied (hence it is non-fungible);
You can screenshot and copy it like painted art, but there is only one original.”
