SDCToken Shadow Cash  (Airdrop Round 1)

https://bitcointalk.org/index.php?topic=2321896.0

https://docs.google.com/forms/d/e/1FAIpQLSf-Mot2xVDoBhWLVSoL4oS6ovCBZAFzl6rhLLQFQBCmBmO9hw/viewform

To apply for the airdrop you must follow them on Twitter.

Airdrop - you only have to fill a form and then receive the tokens for free.
Bounty - you must work for tokens (you are required to do different tasks, like following dev`s twitter, retweet some of his tweets, join his telegram group).

This airdrop is marked as a scam for asking private key - quoting https://airdropalert.com:

KITE  (KITE)
**Website deleted** Kite changed their google form to ask for ETH private key after we listed them on our site. NEVER GIVE YOUR PRIVATE KEY.

We no longer direct people to Kite"

Your ID is 1235733, you can find it in the link - in your browser and your profile link is:

Also, a new airdrop - as usually, a semi-bounty because we have to join telegram, follow twitter and retweet:

Ethereum Platinum

Here is an airdrop who doesn`t care if you have newbies accounts, instead they require to follow twitter and to tweet about their site (no registration requires, detalis must be sent via email - don`t forget to specify the country you reside in). Sound fair to me, since I`m still a newbie myself 
https://btcetoken.com

You can`t really tell for sure whether an airdrop is a scam or not, but I follow a few rules: never download and install a new wallet and never send money to project`s dev. And, of course, never ever send your Private Key or Keystore File (UTC / JSON), but I guess this have common sense for an intelligent person (surprisingly, I`ve heard that many persons do fill their Private Key into the registrations forms   ). Also, setting up a new email address for registrations might be a smart move if you don`t want to risk having your personal email bombarded with spam.

If you have enough time and patience you can spot/ hunt them on twitter or in the Bitcointalk announcements:
Bitcoin Forum > Alternate cryptocurrencies > Announcements (Altcoins)
https://bitcointalk.org/index.php?board=159.0
Also, many Bitcointalk members recommended airdropalert.com - several time - and a few other websites, twitters, telegram groups, so I advice you to take your time and read the comments on this topic at least few pages back.
And last but not least, you can check this topic too, I found many aidrops here and most of them were posted fast enough to allow me submit my registration.

SparkyU, this one looks like it was made by you    No new accounts and they require people to send PM.
ICOBank airdrop. Unfortunately for me (being Newbie), they only accept bitcointalk jr member accounts or higher.

Civilianz Coin is doing an airdrop right now (a mix of bounty & airdrop since you must join their telegram group). No new wallet to be installed, you need MyEtherWallet.
https://bitcointalk.org/index.php?topic=2303113.0
You can register on their website: https://www.civilianz.me
On October 25th the tokens allocated for the airdrop will proportionally be split among all the participants.

So, to avoid whale manipulation  we should pay for getting the airdrops?!?

I don`t want to risk my $ hoping to receive some tokens wich may or not arrive (because if you changed the rules once, you can do it again), but I`m sure that whale you`re talking about surely affords to pay thousand of dollars if he really wants your tokens 

That minimum transfer required 0.002 ETH ~ $0.60 x 3,500 submissions = $2,100.00 . Not bad at all...  There are so many airdrops these days and we can`t say for sure wich one is legit or not, lots of them only collect our email addresses and any other info. So far, Copy Trader project succeeded to get my email address...

I`m very disappointed in you.

I didn`t know about the possibility to find a token using its ID when the buffer in the exchange isn`t not working properly, so thank you for info. Many thanks for the transfer too, the tokens arrived! 

I`m number 776 on the list and I still haven`t received the tokens you sent yesterday to the first 790 persons. Can you please check? Thank you!

No, there isn`t an easier way to add new coins in MEW, you have to do this manually for each coin - the advice was not to bother to add them since you can see all the coins you recived if you just check your wallet on etherscan or ethexplorer: https://ethplorer.io/address/XXXXXXXXXXX or https://etherscan.io/address/XXXXXXXXXXX (put your MEW instead of all that X).
There are many airdrops and you don`t even know for sure that you`ll receive tokens from all of them, so it could be a waste of time to add all the tokens manually.

Everybody can join, there isn`t required to input your Bitcointalk profile to complete registration. Just check their form and you`ll see, they also offer some bonus for joining the BitsyncTelegram group or Twitter.

I didn`t find the official thread on Bitcointalk, I registered directly on their website. The above link points to the registration form.

Bitsync Airdrop started. You will get 250 BITC, but there are also other rewards. There is no need to download a wallet. BITSYNC is future generation crypto exchange and wants to build Ehtereum based Blockchain exchange.
