By joining the waitlist, you get a random place in line similar to a lottery. If your number is called you will have a chance to purchase. Being on the waitlist or pre-funding DOES NOT guarantee a NFT.
You can select an available Drop ahead of time and "Join the Waitlist". When the Drop opens you'll be assigned a random place in line and when called, you'll have the opportunity to purchase the NFT within a certain period of time (about 10 minutes). This makes it convenient so you don't have to join the waiting room 30 or 60 minutes before a drop opens. However, you still have to manually purchase when your number is called.
Waitlist:
1st Priority = VIPs
2nd Priority = Pre-funds
3rd Priority = Open Buy
Additionally, some Drops have the option to "Pre-Fund This item" and the system will automatically purchase the NFT when called so you don't have to be present to buy it.
When users are called on the waitlist those who have pre-funded will have their purchases automatically completed. In order to do this, you need to pre-fund the Drop ahead of time with your credit card or TFUEL.
Users who have not pre-funded will have 10 minutes to purchase at a first-come first-serve basis, considering you have enough funds in your account. If there are any items left over, the sale will switch to Open Buy.
NOTE: Waitlisting does NOT guarantee you will get a NFT. People in the waitlist are called in random order so everyone gets a fair chance.
NOTE: Your place in line may *NOT* be called, for example, if there are more people in line than available NFTs. This ensures a fair system for all interested buyers of a limited quantity of NFTs.
