This TIP based only on my experience how to know if the airdrop is fake

Few months ago i encounter a fake airdrop using a TELEGRAM BOT.
An airdrop bot pretending as a real airdrop of a coin already listed on CMC

How i find out if they're scam or not?
First i search the name of coin on COINMARKETCAP from there i saw the legit website of that coin..
Second i search the TELEGRAM GROUP CHAT link from the WEBSITE of coin
Then i ask the ADMIN in TELEGRAM GROUP CHAT if the airdropbot i saw is legit or not and they said to me its not legit..the COIN that using airdropbot i encounter are using only the name of their coin.


Another FAKE AIRDROP i saw last month is BITAIR, BITAIR asking for selfdrop to buy their token
i search the BITAIR WEBSITE and i find it.i see the TWITTER account from there website
and i notice on there last post was november 2017 if im not mistaken, and bit air ico sale was ended last november.

Both of this type of airdrop are SCAM, I noticed they both collecting a member for their TELEGRAM CHANNEL and collecting FOLLOWER on their twitter account, And asking for selfdrop then dissapear after of ICO Sale.

I hope this post can help some NEWBIE to avoid to be a victim of airdrop with selfdrop SCAM SCHEME.

Any other tip on checking if airdrop is legit?
