# The 3 Sale Cards

Now that you know the format of our IDOs, we should take a look at the different sale cards that you can use to stake your IDIA & vIDIA during our sales.

## So, what are Sale Cards?

Sale Cards are the place for users to stake their IDIA/vIDIA during our Sales. \
\
Every IDO has 3 type of Sale Cards:

* **Standard Pool**
* **Unlimited Pool**
* **Whitelist Sale**

## Standard Pool

In this pool, there is a Staking Cap/Limit to ensure everyone gets their share of the pie and that no whale can come and get it all.&#x20;

The specific amount you can stake varies for each IDO, but generally, the maximum stake per user is around 10,000 IDIA.

## Unlimited Pool

In this pool, you can stake any amount of IDIA/vIDIA tokens, without any limit.&#x20;

There's no maximum amount, so feel free to stake as much as you want. Just keep in mind that others can also stake their tokens in the same way.

## Whitelist Sale

The last sale card is only visible for winners of Marketing campaigns.&#x20;

Throughout the IDO we will do different activities about the project being launched and reward some lucky winners w/ whitelist allocation.&#x20;

For this sale card, there's no need to stake: whatever value you see on the card, you are *whitelisted* to purchase it!
