How can we gain more tokens from airdrops?
How can we identify if its a fraud or not?
Legitimate airdrops come from hard forks, only.
There is an "airdrops calendar" site which announces hard forks and other airdrop opportunities. Those other airdrop opportunities are mostly ponzi schemes. If they're asking you to give them bitcoin in return for the airdrop, it's a ponzi scheme.
A true airdrop requires you to do nothing, but own Bitcoin or some other currency in a wallet with private keys. You should NEVER have to give anything up. And their claims of "daily interest" is just fraudulent lies.
Airdrops are rare, most newbies confuse airdrops with income or bounties.
Thanks, because some people think for their own benefit on the web, even they will have to cause the harm in other people. Thanks for the advise.
