First, let´s look at the difference between these three concepts:
Airdrop: drop of some free tokens that already exist. No cost.Launchpool: drop of some free new tokens. You normally have to earn, stake, hold, farm some token and then you receive free tokens from a new project that is going to be launched. No cost. Launchpad: this is a pre-sale for a new token. You buy it in advance, so you have to pay for it, but at a really low and cheap price.  

I´m a translator and an artist so I need to calculate by myself to understand this, so I will share you what I have learned about this.
Basically this is what we call PASSIVE INCOME, that our money works for you.
If you are a HODLER, you buy and keep your crypto, then check if you want to just leave them there so your tokens give you free tokens.  
So then, what can you do?
Have your money in some place like SPOT. So if you have 1 BNB, you will have 1 BNB always. Value is different and can change. It can be $200 or $700, more or less. But your crypto is safe. You just wait. If you have BNB in BNB vault, flexible or locked earns, staking, you can receive some extra free BNB. So some day you can have 1,1 or 1,3 BNB. More than 1 that it was your original investment. You will add some extra tokens of BNB or other type.

December 2023, example 1 $BNB Let´s calculate.
If you have 1 BNB in BNB VAULT (Flexible earn, you can redeem it any time) for 0.03% APY and an extra 0.35% for first 1 BNB.

So, if you leave it in SPOT, after 1 year, you will have just only 1 BNB.
Imagine, that value is always same $300. If value is more, then you will have more, of course. But here I´m trying to explain to you, that you will have extra tokens for free.
If you keep it like this all the year 2024. Flexible earn #BNB Vault, 0.38% = $301.14 Locked BNB 30 days, 1.9% = $305,7 Locked BNB 60 days, 2.3% = $306.9 Locked BNB 90 days, 2.5% = $307.5 Locked BNB 120 days, 3.5% = $310.5  
For flexible earns, you can redeem it any time. Interest and tokens are distributed daily.
If you unlock your locked BNB before the period is finished, you will loose all the extra tokens, ok?
There are also other type of Binance earn with Dual Investment with 16-61%, liquid swap or Defi Staking, but you have to be a pro trader to understand all that. So I´m just sharing the basic and easy earnings.
APR = Annual Percentage Rate. It can be changed any time. What you can earn in a whole year.
And apart from that, earning more BNB, you automatically participate in #Launchpool

So for new projects you will have FREE tokens from them.
Just for December we had 3 projects so far. So if you HODL BNB (and/or some stable coins), you had these extra tokens for free.
If you have some BNB in BNB Vault or Locked will automatically participate in Launchpool, you don´t need to do anything.
Check always rules and details of each project.
If you had just 1 BNB, you may have received this, after only one week farming, holding, earning.
ACE 0.5 x $11-17 = then sell in Market $5.5 – 8.5 #NFPrompt 6.5 x $1.2 = sell in Market $7.8 #AI ¿? Just HODL, stake, farm, and wait until 4th January to trade it.
There have been already 80 projects of Launchpool. Did you miss them? It´s still not late.
Final conclusions:
So let´s think we have 2 launchpool in one month, $7 average for each one, every 2 weeks. $14 for one month.
APR will be 56%, passive income $168 in one year just for 1 BNB ($300).
Isn´t that great? Our money is working for us.
Now it is farming this one. #AI

And for Launchpad, well…
when we had some project, we could participate and depending on others, we receive some amount of allocation, then we pay for it.
Be careful with this. It will cost you some of your BNB, but it is generally a cheap price for new tokens. That will better for next article, when we have new project I will explain again about this.
Hope you understood the basics. Or feel free to ask again any details.
And I´m ready to recieve any tips if you earned as me with this. Thanks!
