1) Mostly Airdrops are Fake and Ppl are doing it for referral:Stay away from unauthorized airdrops. The primary purpose of most of the airdrop is to collect your email address and other details for following purposes:
1) They will make a database of emails and will sell database to future projects and other marketing agencies.
2) Many of the USers will put same email and password as they are using in exchange for wallets. So that they can cheat you.
Stay Away Guys!!!!
2) Stay Away from Email for claiming the Forked coin I got an email with sender address
noreply@dadi.tech with the subject
Ethereum Hard Fork (Casper)Myetherwallet address link in this email is a spammy link. Never apply your Pvt key...
NOTICE THOSE DOTS BELOW M AND E IN THE URL.
3) Never judge an ICO through ICO rating website.As these rating can be sponsored. I have seen few cases where top rating sites gave a rating of 5/5 and later they removed it from their website. There are chances that they have their share in ICO rating.
4) Stay Away From So-Called Cloud MiningI have invested in many Cloud mining and sharing my personal experience. Most of these minings are a scam you will not be able to recover your invested amount.
