the simple thing to do if you are newbie is just following the chart, never believe on people, whoever it is. if you want to trust people, just trust closer, or do research on every people. but the best part is just believe yourself
But I think for beginners it is difficult to do because they do not really understand and understand what cryptocurrency is or should be done in cryptocurrency and I think for beginners they will be confused to start from where and the easiest way is to ask the opinions of others but sometimes these people actually take the opportunity to fool the beginners and take advantage for themselves because they know the beginners will certainly be easy to believe what they say.
