Free money does not exist, it is a myth created by some crafty people to mislead newbies into sharing stuff that they should not for their own safety, like personal details. If you want money you have to work for it or sell your stuff, nobody is sitting out there to shower free bitcoins on you, this is no charity going on here and neither on the internet. There is always some catch involved in free tokens or shitcoins.

Airdrops will give you shitcoins, that might never actually go up and your wallet will get filled with such tokens until you stop collecting them yourself. Like I said, most of the airdrops ask for a long of personal info and you should be careful.
