When the sale is complete, claim the $XXX tokens you've bought.
Done! In the case of an overflow you can reclaim your remaining MMF tokens.
What is the “Overflow” sale method?
TLDR: Basically, the more you put in, the more you will get, and you’ll get back anything that doesn’t get spent.
In the “Overflow” method, users can subscribe as much or as little as they want to the Launchpad, and their final allocation will be based on the amount of funds they put in as a percentage of all funds put in by other users at the time the sale ends. Users will receive back any leftover funds when they claim their tokens after the sale.
It's possible to receive no tokens at all: If you commit a very small amount of MMF compared to the total amount committed by others, your contribution may be such a small part of the total that you may not qualify for even a small portion of the tokens sold.
In such a case, you will still be able to reclaim all the MMF tokens you committed.
What happens if the Launchpad doesn't raise all the funds targeted?
The sale will proceed as normal, and all funds contributed will be spent.
