Too good to be true

Guaranteed returns

Promises like “2% per day” or “risk-free profit” are how Ponzi schemes work: early users are paid with new users' money until it collapses.

Fake giveaways

“Send 1 ETH, get 2 back” videos with famous faces are fake. Nobody doubles your coins.

Pressure

“Only 10 minutes left”, “last chance”, “do not tell anyone”. Pressure is there to stop you from thinking.

Simple rule

If someone promises profit, wants you to hurry, or asks you to send money first — stop.
