Yes so true! In my mew, there are lot's of shitcoins there that i got from scam icos and airdrops. But sometimes shitcoins or scam coins can make us a lot of money too! Funny thing is that even scam coins tries to list themselves in exchangers and their devs are the ones who dumps first then goodbye! When we receive coins better we try to research if it has actual product or project. And better be the first to
sell if your instinct tells you that the coins doesnt go anywhere far than scam.
