Nobody gives anything for free, right?
Well that is exactly what an airdrop is. A true airdrop is when somebody gives you some cryptocurrency just for signing up or doing some menial tasks.
The downside of airdrops is that sometimes the coins that you are given have little or no value. A coin that is being launched needs to build a base before it can gain some valuation. Also, it could be a few months before they are listed on an exchange and become tradeable assets.
The unspoken promise of the airdrop is that by getting in early you may end up with an asset that balloons in value as it reaches maturity.
Probably the easiest airdrops to participate in are those offered by Atomic Wallet. All you have to do is download and install the wallet. Click on the link HERE to get Atomic wallet.
They pay out 10 AWC tokens for signing up to the wallet, and an extra 5 AWC can be earned by entering a PROMO code on signup (mine is 14EA0T). The AWC token is currently trading around USD 0.62, after having experienced explosive growth of over 200% in the month of June.
Once you have installed Atomic wallet you will notice that not only can you use it to store your crypto, you can also earn some more by staking (see my post on that HERE) and other airdrops inside the wallet.

As you can see, there are currently two tokens you can receive as airdrops. To be eligible all you need is to hold over 100 TRX in your wallet at the cut-off date.
The Just tokens are distributed on the 20th of each month. You get 1.1 JST tokens for every 100 TRX. The current value of JST is about 0.005174 USDT, while 100 TRX amount to 1.58 USDT, the airdrop comes out as a 0.36% of the Tron balance, or about 4.26% annually.
Wink tokens are distributed on the 28th. You can collect 1 WIN for every 100 TRX, but as they are worth only about 0.00007 USDT, your percentage return is miniscule.
And that is basically how it goes with airdrops. The dollar amounts are very small if you look at the current value of the crypto offered. Airdrops are a way to promote crypto projects. The people behind the airdrop are just trying to get the coin out into the public to generate some interest.
Do not be fooled by airdrops claiming to be worth hundreds of dollars. In this space there are many scams, and you could easily fall victim if you give in to outlandish claims. If it sounds too good to be true then it probably is.
I have as a rule never to pay out any money to be eligible to withdraw funds from an airdrop. It may seem quite silly the small amounts they may ask, but if the coin itself is worth almost nothing then paying anything is just throwing your money in the trash.
