Crypto is not scam just some person make bad project and give label for crypto become scam, never heard some one want to make crypto scam because always chance give us for you get profit with investing in bitcoin and altcoin, you can buy bitcoin or altcoin now before you miss chance with buy bitcoin and altcoin with lower price,
yes I agree with you crypto is not a scam it's just a crypto to be a scam because it is in the wrong hands. and I think cheating is also common in fiat currencies and we can't avoid it. because in this world there are always bad people who want to get profits faster without having to work. so this scam is not a crypto error but a user error.
