I've brought in an article that talks more about btc scam and how to avoid been a victim, is Bitcoin investment safe, factors to consider before buying btc, risks associated with btc, ICO's scam, crypto pump and dump schemes, keeping your crypto safe in wallets, Bitcoin security and privacy and lots more come along with this package.
ICOs are ICOs, they are not bitcoin. In most cases, you shouldn't invest in ICOs/IEOs or whatever new trends they came up with anyways. Pump & dump schemes also have nothing to do with bitcoin. With those schemes, the organizers get you to buy a worthless coin where they are the bag holders and you are buying from them filling their pockets. Use well-known, proven, open-source, and non-custodial wallets and you should be fine if you know how to secure them.
Bitcoin is safe. It's the people who make something good or bad. If someone scams you and steals your bitcoin, it's not the network's fault. It's you who didn't know better and fell victim to whatever tricks someone played on you. Anything can be good or bad. A gun can save your family's life in case someone tries to hurt them. But a gun can also be used to take someone else's family from them. You can use a car to drive your kids to school or use that same car to drive over kids on their way to school.
