Crypto Airdrops Scam Alert

Everyone loves free money . And With the rapid progress of Crypto Trading many organization decide to drop some of their token worth some few bucks.It takes a while for one to participate and receive Airdrop .
How to know
An airdrop also plants a seed , When you look at Coinmarket cap you will see a list of thousand coins. Just on page one you can see 100 coins listed. However if you have or had a coin that name is still in your brain. The seed is planted and whenever you check Coinmarketcap and scroll down, the name of the free e-Coin will jump out and people will check how it is doing. It is just advertising technique. For sure not all Airdrops are genuine . There are many fake Airdrops going right now. i searched for this topic on Bitcoin talk and someone there said: etherdoge was a scam. the scammers distributed the airdrop to ethereum wallets but put a lock on the tokens so that they could not be sent.
if folks tried to send tokens, the transaction would fail and the user would still be charged gas
meanwhile, the devs liquidated a whole bunch on etherdelta to unsuspecting buyers.
Most people consider the ICOs requiring donation are all probably Scam. And most skeptic people consider the ICOs using Google forms are fake for sure , Maybe not . You cant say for sure. The biggest problem is that we have to wait for several weeks and by such time we may even forget.So basically i message in their Telegram Group and notice the way they reply me.I participate in lot of Airdrops using my fake Facebook and Twitter profs and hope for some of them to be true.
