dear friends im a newbie did lots of air drops and received lots of coins.some are telling those coins are scam.
eg-piggy,ohni
how can i identify whether they are scam or not?
If it's too good to true then it probably is. Remember that.
If it is asking for your investment then always always check and do your own research and determine whether or not it's a good investment to make, whether or not their promises are actually fulfillable or just marketing strategies.
Airdropped coins should also be treated with caution. They will probably turn out to be nothing at all.
