I think that most of the time we do not lose money because of hackers or scammers but because of unsuccessful investments or if someone is doing trading then also because of trading. For example if some beginner decides to invest not in Bitcoin but in an altcoin it does not matter which one I see that all altcoins are performing very badly right now so most likely they will lose money and lose quite a lot. So I believe we lose money most often because of bad investments in crypto.
Emotions are the bane of any investment.
The key is to get them into the right direction, so that they wouldn't take the lead in your decision-making.
A few steps should be taken to invest. First you have to select the right coins. Secondly, in the amount of investment in the amount of money you will not have to suffer any harm. I think Bitcoin is a coin that does not have any risk without doing it. In this case, no technical analysis is needed, only to be patient with patience. However, altcoin has many risk and if invested in a wrong token, you may encounter 50% damage. However, those who are traded in the case of Expert or Altcoin Holder can make the profit if investing according to their advice. However, emotion or conscience applies everything in this regard. This I do not think there will be any harm because people do anything without conscience or emotion.
