Latium HODL Rewards is a system which rewards you for locking up your LATX tokens for a period of time. You can lock your tokens up for 30, 90, 180, and 365 days. If your tokens are held in the HODL rewards for the full lock-up period then you will receive a percentage bonus in LATX tokens.
You can see how much LATX you will earn through the lock-up period by selecting the amount of days and entering in an amount of LATX tokens to Lockup. You will see your projected Reward under the Lockup Reward section
