actually there are. for example during 2017 whoever owned any amount of bitcoin (own means having the private key of the address holding those "coins" not having it on some exchange) received more than 50 different coins for free. all of them are shitcoins but they could all be dumped for valuable bitcoin so it was free money.

but generally speaking you are correct. every time you see someone is promising "easy money" they are most probably lying and are trying to scam you.
