More and more people are choosing to participate in Exchange initial offerings, and this is understandable.
Firstly, the exchange independently and meticulously checks and selects projects. Secondly, it is a guarantee that the purchased coins or tokens will be traded on the exchange.
The risk of scam is minimal.
The risk of being scammed goes down if you participate in ieos instead of icos but it does not guarantee that you are going to make any money, after all there are many reasons why a coin may fail, and even if you invest in a coin that eventually becomes successful there is no guarantee either that you are going to be holding your coins for that long, there are many people that invested in ethereum and bitcoin when they were very cheap and sold their coins for a fast profit and they are still lamenting that huge mistake.
Sure, man, you are right. Success mostly depends on investors skills, patience and ability to wait, and some part of luck, oh course. Not all those who invest have everything necessary to succeed.
Many believe that you can be successful by just selecting the right coin but as you have pointed out you need many other things to become successful and many never cultivate those skills, just to give an example many believe they can be patient and wait until the market recovers and yet every day I see more members being desperate to get profits when bitcoin just went through a recovery recently and altcoins gave good enough profits until the summer of 2018.
