When recalculating the holder bonus, you do not earn less.
On the contrary, you earn more: after all, when you add NMX and USDT to liquidity, your share in the main pool grows, and therefore in the bonus pool. Accordingly, your daily income from personal farming is growing.
You can also reinvest unclaimed NMX farming coins without losing the holder bonus if you add additional USDT from your connected wallet to the pair. We talked about this in more detail in this article.
Why do we recalculate the holder bonus?
Let's first understand what a holder bonus is and what it is charged for.
The holder bonus only increases when farming from the bonus pool.
The shares in the main pool and in the bonus pool are the same, but the sizes of the pools are different.
For example, if your bonus pool share is 1% of 1300 NMX/day and you hold liquidity for 7+ days, you will get +20% to your bonus pool stake – meaning you will be farming with a larger bonus pool stake at that time while the pool size does not change.
But this is not +20% to your total income from the main pool, or the main and bonus pool. This is important to understand.
Since the share in the bonus pool is equal to your share in the main pool and is accrued during your liquidity hold, when the share in the main pool increases, the holder's bonus also increases, as your share has grown.
But at the same time, you do not keep the amount added to liquidity for the entire time (how long you keep your first deposit), you keep it less, and recalculation is necessary accordingly.
Let's take an example:
The user invested 10 USDT in staking and held it for 365 days, thereby increasing his share in the bonus pool by 900%. And then I decided to stake another 1000 USDT.
In this case, the staking time is proportionally recalculated.
The arithmetic weighted average of staking days for the new amount will be calculated using the formula: (10*365 + 1000*0)/(10 + 1000) = 3.6 days. Round up to whole days = 3.
That is, when the amount of staking is increased from 10 to 1000 USDT, the coefficient of increase in profitability in the bonus pool will change in accordance with the total amount and number of days of staking and will become equal to 3.
This means that to activate the +20% multiplier, but from the amount in the pool of 1010 USDT, you will need to stake for another 4 days.
We remind you that the holder bonus is reset completely if you have connected your wallet to another account, removed any amount of NMX-LP from liquidity, or linked the wallet to the account, if this has not been done before.
