Lately I have realized most people call crypto currency fraud because they chase green candles , news online before buying tokens.
The proper steps to take is to get the news, verify the source and Do Your Own Research
Then no one would fall into scam icos
There is another one. Do your own analysis. Don't just depend on what your friends say, even if you trust them, it's not like they can predict the market so learn to do your own job and verify every information you come across.
