If you contributed KSM to Altair in the Kusama Crowdloan you will get an additional bonus (5 %) on your CFG rewards when you contribute your DOT to Centrifuge in the second batch of the Polkadot auctions.
In order to make sure that you will get the Loyalty Bonus (also known as the Double Trouble bonus), you have to contribute your DOT from the same account as you contributed your KSM from.
If your DOT is not already in that account, use these simple steps to find your DOT wallet address in your account.
1: Open your extension and find the account that you used for the Kusama crowdloan and change the chain to “Polkadot Relay Chain” to display your DOT wallet address.
2: This will display your DOT wallet address in the extension for that account. A DOT wallet address always starts with the number “1”.
3: You can now transfer your DOT to this wallet address (from an exchange or another wallet) and connect with this account to the Centrifuge crowdloan page and contribute your DOT. Remember to keep the chain on “Polkadot Relay Chain” when you are you contributing.
Notice that you need at least 6.1 DOT to contribute - 5 DOT minimum contribution, 0.1 DOT for transfer fees and 1 DOT left on your account to keep it alive (Polkadot existential deposit).
